Product details
The Terasaki 003448 is a 24 V DC shunt trip for TemBreak 2 Lite breakers on the 160 A and 250 A frames. 24 V DC is the usual control voltage of PLCs, safety relays and fire alarm interface modules, so this coil lets those systems trip the breaker directly or through a small interface relay.
Key features
- 24 V DC coil with a permissible range of 18-30 V DC (75-125 % of rated)
- 0.03 A peak exciting current
- Rated for continuous energisation; there is no anti-burn switch
- Main contacts usually start to open within 30 ms of rated voltage
- Takes the breaker's one trip-coil position, so it cannot be combined with an under-voltage release
Typical applications
Automation and building services panels where a PLC output, a BMS controller or a fire alarm interface trips an outgoing way, and load shedding from an energy management system. Pair it with an alarm switch so the controller can see that the breaker has opened.
Suits the S160-SCJ (160 A frame) and E250-SJ, S250-SJ and S250-SN (250 A frame) from the TemBreak 2 Lite range we sell. Auxiliary and alarm switches fit alongside it.
