Buying guide

A shunt trip is an internal accessory that opens the MCCB on command: energise its coil and the breaker trips. It is the usual way to connect a fire alarm interface, an emergency stop or a building management system to a distribution board.

Terasaki makes two families: one for the TemBreak 2 Lite devices (E160-SF, S160-SCJ, E250-SJ, S250-SN, S250-SJ) and one for the TemBreak 2 devices up to 400 A. Both come in AC and DC coil voltages. Filter by the coil voltage and by the device series the release fits; each product page lists the MCCBs it is made for.

Questions

What does a shunt trip do?
It trips the MCCB when a voltage is applied to its coil, so a fire alarm panel, an emergency stop or a building management system can open the circuit remotely.
Which coil voltage do I need?
The voltage of the control circuit that will fire it: 24 V DC for most alarm and control panels, 200-240 V AC where the trip circuit is mains-fed. AC coils cover a band; DC coils are fixed.
Can I fit a shunt trip and an under-voltage release?
No. Each TemBreak 2 MCCB has one trip-coil pocket, so it takes either a shunt trip or an under-voltage release. Auxiliary and alarm switches fit alongside.
