These products are used whereverthere is a demand for electricalpower in residences, high-riseapartment and office buildings,commercial sites, hospitals and factories.

Built With Experience

For over a century, Eaton hasfocused on providing qualitypower-centric products andservices. In todays businessenvironment, customers likeyou are driving our transformation from a leadingglobal electrical componentsprovider into a customer-centric solutions partner whounderstands your business.We do this through in-depthcollaboration with customersand subject matter expertsstudying the issues inherent to the electrical power distribution and control systems.

Eaton is one of the pioneeringelectrical manufacturers andhas been focused on providingreliable backup power systemswith transfer switchequipment for over 75 years.

Powered With Innovation

Eaton continues to meetchanging industry needs by providing a broad range of automatic transfer switches.These switches may begrouped into a basic, enhanced or premium set offeatures that will meet yourapplication requirements. Eaton has used industry-leading breaker based designsfor years and now has a line ofcontactor based designs.

These designs can be matchedto a family of automatic transfer switch controllers thatwill meet your specific needs.Identify your application,define your needs, and selectthe solution from Eaton.

Delivered With Reliability

Power outages due to badweather or utility failure havegrown increasingly costly andmore disruptive to businessesand homeowners. A backuppower system will keep yourcomputers, security system,heating or refrigeration system, cash registers, homehealth care equipment, or anysystem that uses electricpower, energized and operational. The demands forreliability have increased.Eaton meets thoseexpectations by the stringentCSA C22.2 No. 178 andUL1008 automatic transferswitches with a world-classproduct delivery system.Eaton will provide the individual transfer switch builtto exacting standards or supply the same transferswitch in an integratedlineup with other Eaton gear.For startup service, applicationsupport, and emergency support, call Eaton ElectricalServices and Systems at 1-800-498-2678.

Front Access

Front access is a standardfeature. Source-1 (NORMAL)Source and Load connectionsare set up as standard topentry and Source-2(EMERGENCY) Source connections as bottom entry.These connections are locatedin their own separate compartments. These connections can be relocatedin the field if necessary.

Multi-Tap Transformer

The industry-exclusiveMulti-Tap system voltageselector allows the transferswitch to be applied on mostsystem voltages by properinsertion of the selector plug.

Draw-out Contactors

The ATS and the Bypassdraw-out cassette powercontactor designs are identicaland interchangeable. Thisstandard feature allows theuser the ability to withdraw,maintain or swap contactorassemblies, providingredundancy of ATS and Bypassfunctions from one contactorassembly to the other.

Improved Safety

The unique Eaton designincludes separation betweencontrol and power components. The ATS andBypass isolation contactors aremounted in separatecompartments with protectivebarriers between them. Thisdesign prevents the possibilityof contact with the rear-mounted power connections to the contactors.In addition, the top and bottomentry have separate compartment doors.

Ease of Maintenance

Transfer to the Bypass powercontactor is easily initiated andcontrolled via door-mountedcontrols. Once the transfer tothe Bypass contactor iscomplete, the ATS contactor is easily racked out with thecompartment door closed. The ATS contactor may thenbe tested in the racked outposition.

Ease of Transfer

The Eaton design allows theoperator to make a quick andsimple transfer from the ATSpower contactor to the Bypasscontactor by initiating theelectrically operated transfervia a 2-position switch. Doormounted indicating lightsconfirm that a successfultransfer has taken place.

Dual ATS Capability

The controller on conventionalBypass Isolation Switches onlycontrols the ATS contactor.The Eaton design allows theswitch controller to remainactive in both the ATS andBypass modes, thus providingcontrol to either contactor.This ability of the controller toremain active and control theBypass isolation contactorprovides "N+1" redundancyof a second fully functioningATS, a feature unique to Eaton.

Superior Main Contact Structure

The Cutler-Hammer Combination Bypass and AutomaticTransfer Switch is listed to CSA specifications C22.2 No. 178 and C22.2 No. 31.

As an added plus the switching devices are listed under CSAC22.2 No. 5. Completely enclosed contacts provide both safetyand reliability. They also ensure the integrity of the contactassemblies and minimize the need for periodic maintenance ofthe contacts, reducing the need for downtime and maintenance time.

Breaker-basedTransfer Switches

Switch Type - Bypass Isolation

Transfer Switch Is Easy To Maintain And Test

The Cutler-Hammer Bypass/Isolation Switch is designed torequire minimum maintenance even under the most strenuousof operating conditions. Due to the use of moulded caseswitches and their inherent self-protection capability, the contactstructure and mechanism is extremely long lived.

Our experience has shown that through normal operating conditions, the moving and stationary contacts will maintaintheir integrity for the full expected life of the transfer switch.

When isolating and bypassing the transfer switch, a short term(less than 3 second) power interruption results. However, thisis less than when transferring power after a power outageusing a standard transfer switch. Also, with a double-sidedbypass the transfer switch can be bypassed to either sourcequickly and easily regardless of the position or condition of the transfer switch.

Safety To Maintenance Personnel

In most instances, the Bypass/Isolation Switch will be in theBypass Mode only during a maintenance or testing period.During this time, there could be operating personnel close tothe equipment. The self protection capability of theCutler-Hammer switch would give these operators an extrameasure of safety during a rare coincidental fault condition.

Features

The Cutler-Hammer Bypass Isolation Switch is available with all the options and features of our standard Transfer Switch product line. Proven, microprocessor based programmablecontrollers are supplied as standard on all Bypass TransferSwitches.
