1. GENERAL

The SE-107 is a combination ground-fault and ground-check monitor for resistance-grounded systems in non-hazardous applications. The ground-fault circuit is latching and the ground-check circuit is typically non-latching. One output contact is provided for contactor control or for undervoltage operation in a breaker trip circuit. Ground-fault current is sensed by a CT200-series current transformer. A trip level of 0.5, 2.0, or 4.0 A is switch selectable for use with a 5-, 15-, or 25-A grounding resistor. Enhanced filtering eliminates false ground-fault trips from adjustable-speed-drive harmonic distortion. Trip time is adjustable from 0.1 to 2.0 seconds. The fail-safe ground-check circuit is validated by an end-of-line termination with a 5.6-volt Zener characteristic. The Zener characteristic clamps induced voltage and allows induced current to flow in the ground-check loop. Consequently, induced-ac-withstand capability, noise immunity, and open/short detection are independent of current in the phase conductors. Enhanced filtering prevents false ground-check validation due to an active chopper condition. See www.littelfuse.com/relayscontrols for Technical Note GC-1. CAUTION: The SE-107 is not a lock-out device. Follow lock-out procedures for maintenance.

2. OPERATION 2.1 SETTINGS 2.1.1 GF TRIP TIME Ground-fault trip time is adjustable from 0.1 to 2.0 seconds. Time-coordinated ground-fault protection requires this setting to be longer than the trip time of downstream ground-fault devices. 2.1.2 GF The ground-fault-circuit trip level is 0.5, 2.0, or 4.0 A when current is sensed with a CT200-series current transformer. Since the ground-fault-circuit trip level should not be greater than 20% of the grounding resistor let-through current, these levels are appropriate for use with 5-, 15-, or 25-A grounding resistors. For other applications, the trip level of the ground-fault circuit is 0.25, 1.0, or 2.0% of the primary rating of the 5-A-secondary current transformer.

2.2 OUTPUT RELAY The output relay operates in the undervoltage mode. It is energized and its contact is closed when the ground-check loop is valid and the ground-fault circuit is not tripped. The undervoltage mode is referred to as fail-safe because: Undervoltage devices release if supply voltage fails. Undervoltage ground-check circuits do not allow

cable couplers to be energized until the ground-check loop is verified.

2.3 INDICATION AND RESET The blue POWER LED indicates that the internal power supply is on. The red GROUND FAULT LED indicates a ground-fault trip and the green GROUND CHECK LED indicates a valid ground-check loop. When a ground-fault trip occurs, the SE-107 remains latched until the reset switch is pressed or the supply voltage is cycled. The ground-check circuit is non-latching and does not require a reset. Terminals are provided for remote indication and reset as shown in Fig. 1. For the latching ground-check (Option L), the GROUND CHECK LED is red and it indicates a latched ground-check trip. 2.4 FUSING The output contact is protected by fuse F1 (4.0 A, time delay). The ground-check circuit is protected by fuse F2 (0.5 A, time delay).

3. INSTALLATION 3.1 SE-107 SE-107 outline and mounting details are shown in Fig. 2. Typical connections are shown in Fig. 1. Connect supply voltage to L1 and L2. For a 120-Vac supply, connect supply neutral to L2. For a direct-current supply (Option D), connect supply negative to L2. Connect chassis-bonding terminal to ground. Connect contact terminals A and B as required. Faceplate LED’s are driven in series with remote-indication LED’s. When a remote kit is not used, terminals CI, +, and GI must be connected for the faceplate LED’s to operate. These jumpers are installed at the factory. Connect terminal GC to the outgoing ground-check conductor and connect terminal G to ground. To meet electrical code requirements, do not jumper chassis-bonding terminal to terminal G. Install the upper terminal-block cover to prevent inadvertent contact with line terminals.

FIGURE 2. SE-107 Outline and Mounting Details. 3.2 GROUND-FAULT CT Outline and mounting details for CT200 and CT200L current transformers are shown in Fig. 3. Pass the phase conductors through the CT window as shown in Fig. 1. Do not pass the ground or ground-check conductors through the CT. In applications that require shields or drain wires to pass through the CT, return them through the CT before connecting them to ground. Connect the secondary of the ground-fault CT to SE-107 terminals CT1 and CT2. The CT connection to the SE-107 is not polarity sensitive. Ground one side of the CT secondary.

NOTE: The CT200 and CT200L are 600-V-rated current transformers. When system voltage is above 600 V, ensure conductors passed through the sensor window are insulated to system voltage.


3.3 GROUND-CHECK TERMINATION Install the ground-check termination at the load to complete the ground-check loop as shown in Fig. 1. Termination outlines and mounting details are shown in Figs. 4, 5, and 6. Use only a Littelfuse Startco termination device; others may not meet performance requirements. Connect terminal G of the termination to the equipment frame so that the ground-conductor-to-equipment-frame connection is included in the monitored ground-check loop. Connect terminal GC of the termination to the incoming ground-check conductor. If ground-check interlocks are used, low-level (bifurcated, precious-metal, or sealed-reed) contacts are recommended. If used as a ground-fault monitor only, install the termination at the SE-107. 3.4 REMOTE OPERATION Terminals SW, CI, , and GI are provided for remote LED indication and remote reset as shown in Fig. 1. Remote LED’s are driven in series with the front-panel LED’s. Remove factory-installed jumpers from terminals CI, +, and GI, and connect a remote kit as shown in Fig. 1. Optional remote kits are shown in Figs. 7, 8, and 9. Standard LED indicator lamps are not compatible with the SE-107. For general-purpose applications, use the RK-105 Remote Indication-and-Reset Assembly or the RK-105I Remote Indication Assembly. Connect terminals SW, CI, +, and GI to remote-kit terminals SW, CI/RI, +, and GI. For 22-mm-component applications, use the RK-102 Remote Indication and Reset Kit. Connect terminal X2 of the green ground-check indicator to CI, terminal X2 of the red ground-fault indicator to GI, and connect indicator X1 terminals to +. For remote reset, connect the normally open push-button switch across terminals + and SW. If indication is required from a separate voltage source, or if separate ground-fault and ground-check contacts are required, use an RK-13 Relay Interface Module. The RK-13 mounts on the SE-107 lower terminal block and is compatible with the RK-102, RK-105 and RK-105I. See Figs. 1 and 10. Contact K1 closes when the GC LED is on and contact K2 closes when the GF LED is on. 3.5 PARALLEL-PATH ISOLATION A PPI-600V can be used for parallel-path rejection. A PPI-600V will also eliminate intermachine arcing and prevent stray ac and dc currents from flowing in the monitored ground wire. See Figs. 11 and 12. See Technical Note GC-10 “Parallel Path Isolator” at www.littelfuse.com/relayscontrols, or contact Littelfuse Startco for application details.

3.6 GROUND-FAULT TESTING Use CT-primary current injection to test the ground-fault circuit. Fig. 13 shows test circuits using the SE-400 Ground-Fault-Relay Test Unit and the SE-100T Ground-Fault-Relay Tester. The SE-400 has a programmable output of 0.5 to 9.9 A for a duration of 0.1 to 9.9 seconds. The SE-100T has LO and HI outputs for 5- and 15-A resistance-grounded systems. A test-record form is provided in Section 8 of this manual. Record the test results and test dates on this form to meet the requirements of the National Electrical Code (NEC). Retain the form so that the test data can be made available to the authority having jurisdiction.

4. COMPATIBILITY The SE-107 is a direct replacement for the SEL-100, SEL-100TD, SE-101, SE-102, SE-103, and SE-105 in fail-safe applications. Terminal designations are shown in Table 1. Terminals CT1 and CT2 are transformer isolated so that the CT secondary can be grounded. Units with old designations do not allow the secondary of the ground-fault CT to be grounded when the ground-check circuit is used.

7. WARRANTY

The SE-107 Ground-Fault Ground-Check Monitor is warranted to be free from defects in material and workmanship for a period of five years from the date of purchase. Littelfuse Startco will (at Littelfuse Startco’s option) repair, replace, or refund the original purchase price of an SE-107 that is determined by Littelfuse Startco to be defective if it is returned to the factory, freight prepaid, within the warranty period. This warranty does not apply to repairs required as a result of misuse, negligence, an accident, improper installation, tampering, or insufficient care. Littelfuse Startco does not warrant products repaired or modified by non-Littelfuse Startco personnel.


8. GROUND-FAULT PERFORMANCE TEST

To meet the requirements of the National Electrical Code (NEC), as applicable, the overall ground-fault protection system requires a performance test when first installed. A written record of the performance test is to be retained by those in charge of the electrical installation in order to make it available to the authority having jurisdiction. A test record form is provided for recording the date and the final results of the performance tests. The following ground-fault system tests are to be conducted by qualified personnel:

a) Evaluate the interconnected system in accordance with the overall equipment manufacturer’s detailed instructions.

b) Verify proper location of the ground-fault current transformer. Ensure that the cable or bus passes through the ground-fault current transformer window, and that the grounding conductors or shields are not encompassed by the ground-fault current transformer in such a way as to cause ground-fault current to be missed. These checks can be done visually with knowledge of the circuit involved. The connection of the current-transformer secondary to the SE-107 is not polarity sensitive.

c) Verify that the system is correctly grounded and that alternate ground paths do not exist that bypass the current transformer. High-voltage testers and resistance bridges can be used to determine the existence of alternate ground paths.

d) Verify proper reaction of the circuit-interrupting device in response to a simulated or controlled ground-fault current. To simulate ground-fault current, use CT-primary current injection. Fig. 13a shows a test circuit using an SE-400 Ground-Fault-Relay Test Unit. The SE-400 has a programmable output of 0.5 to 9.9 A for a duration of 0.1 to 9.9 seconds. Set the test current to 0.6, 2.3, or 4.6 A for SE-107 units set at 0.5, 2.0, or 4.0 A respectively. Fig. 13b shows a test circuit using an SE-100T Ground-Fault Relay Tester. The SE-100T provides a test current of 0.65 or 2.75 A for testing 0.5- and 2.0-A trip levels. Inject the test current through the current-transformer window for at least 2.5 seconds. Verify that the circuit under test has reacted properly. Correct any problems and re-test until the proper reaction is verified.

e) Record the date and the results of the test on the attached test-record form.
