  • Shunt trip S2-A

    These are used for remote tripping of the M.C.B. by applying acontrol voltage. The shunt trip contains a relay with an integratedcontact, that opens after the M.C.B. has tripped and interrupts thecontrol voltage of the relays. This prevents the flow of current incase of substained control voltage.

    Mechanical interlocks

    It automatically releases the relative circuit-breaker when the panelof the electric switchboard is opened or removed. The release isonly mechanical and acts on the release elements of the circuit-breakers.

    Accessories for MCB

    The S2 range of circuit-breakers are supported by a whole groupof auxiliary elements with many functions and configurations. Theseinclude auxiliary contacts, shunt trips, undervoltage releases, signalcontacts, and mechanical interlocks.

    These accessories improve the performance of the circuit-breakerand enables innovative and integrated solutions to be used in everyinstallation.

    Auxiliary contact S 2-H..

    The auxiliary contact can be built on subsequently to the M.C.B.The switching position of the auxiliary contact depends on theposition of the M.C.B. (ON-OFF). Because of coupling to theswitching mechanism of the M.C.B. the auxiliary contact offers atrip-free feature.

    The auxiliary contact can be delivered either with screw or plug-inconnections, the auxiliary contact with 3 potential free contactsonly in screw-in connection.

    Signal contact S 2-S

    It signals the tripping caused by overload earth fault or short circuitcurrent however, there is no signal when the M.C.B. is switchedOFF manually. With a red handle which allows resetting of the tripsignal without the M.C.B. being switched on. It has also a testbutton for checking the control circuit without interrupting the maincircuit.

    Undervoltage releases S 2-UA..

    These are used for remote tripping of the M.C.B. Only in case ofsubstained voltage the relay allows to switch on the M.C.B. Theundervoltage release trips the M.C.B. if the supply voltage isinterrupted or switched off (suitable for emergency off circuits).

  • The ABB range of RCCBs give protection against earth leakage incase of direct and indirect contact to live parts. RCCBs are usedfor protection of earth leakage. To have short circuit and overloadprotection these RCCBs are connected in series with a MCB or fuse.

    'AC' type RCCBs (known as ELECTROSTOP) is used for detectionof alternate leakage current.

    'A' type RCCBs (known as VARISTOP) is used for detection ofalternate/pulsating leakage current with DC components.

    Thanks to an electronic circuit able to distinguish betweentemporary leakage caused by a disturbance and permanent leakagecaused by a fault, the new 'AP' type RCCBs resists a currentimpulse from 8/20µs from and 3000A peak.

    The DS971 range provides protection solution for all types ofsingle-phase circuits in modern installations. It is characterized by aninnovative design with a single red/green two colour operating leverand residual current trip signal on the front of the apparatus.

    The DS971 range satisfies all protection requirements in twomodules, offering the opportunity of choosing between four differentsensitivities (10-30-100-300 mA) and for each of these, thepossibility of choosing between 'A' type or 'AC' type residualcurrent protection with breaking capacity of 10kA. The 'C'characteristic is available with rated current from 6A to 40A.

    The closing velocity of the contacts is independent from the rotationvelocity of the toggle. This is ensured by a trip mechanism patentedby ABB.

    'AC' type RCBO is suitable for all installationswhere there may be loads with alternate faultcurrents.

    'A' type is designed to be used in case ofalternate and pulsating DC fault currents.Their use is typical in installations whereusers are equipped with electronicdevices meant to rectify currents orother physical variables.

    Analogue Time Switches (ATS) - ATS-1, ATS-1R, ATS-7RATS times switches can be used to control the opening and closing of circuits according to a daily or weeklytime schedule, or to manually set operation permanently on ON/OFF. Installation of ATS electromechanic timeswitches is particularly appropriate in all situations where operation of loads needs to be programmedaccording to a daily or weekly time schedule.

    Digital Time Switches (DTS) - DTT-1/1, DTT-7/1, DTT-7/2Installation of a digital time switch in a system is particularly useful in those situations where the programming ofthe operating schedule of the loads needs to be sufficiently flexible to permit variations according to time andday of the week or month.

    Twilight Switches - TWS-1ABB twilight switches turn on the lighting in an installation when the daylight level measured by a special sensorfalls below a set threshold. They are especially useful in places accessible to the public, where they encouragepower savings and increase the deterrent action of lighting in preventing crime and vandalism. Delayedswitching also prevents unnecessary on/off switching in case of sudden changes in the daylight level.

    The new characteristics acc. EN 60 898 are for line protection . They all have the samethermal settings and differ only in their magnetic tripping values.The higher magnetic settings of the C- or D-characteristics are for applications with start orhigh inrush-currents.

    K-Characteristic

    For cable and appliance protection.

    Rated currents 0.5 to 63 A in 17 steps (S 270) or 0.2 to 63 A in 20 steps (S 280). Motorprotection can be achieved by the selection of the M.C.B. with the correct rated currentcorresponding to the motor data. The electro-magnetic trip is set in such a way that themotor starting current does not lead to tripping.

    Due to the higher magnetic non tripping current, in circuits with incandescent lamp groups,mains parallel operated fluorescent lamps or other discharge lamps, the conductor cross-section to be protected can be more economically utilized as compared to a M.C.B. of thesame rated current in tripping characteristic B.

    Z-Characteristic

    For protection of semiconductor devices and voltage transformer circuits.
