Product details
The Terasaki 003431 shunt trip has a 380-450 V AC coil, so a TemBreak 2 Lite breaker on the 160 A or 250 A frame can be tripped from a phase-to-phase voltage. Wired across two lines of a 400 V or 415 V supply, it needs no neutral and no control transformer.
Key features
- Coil rated 380-450 V AC for line-to-line connection
- Lowest coil current of the AC shunt trips: 0.0065 A peak
- Continuous-rated coil, no anti-burn switch
- Contacts generally begin to part within 30 ms of rated voltage reaching the coil
- One trip-coil position per breaker: fit this or an under-voltage release
Typical applications
Three-phase installations where no neutral is brought to the panel, such as motor, pump and compressor feeders, and boards where a 400 V tripping supply is simpler than adding a control transformer. Because a shunt trip only works with voltage present, take its supply from a point that stays live whenever a trip may be needed.
Fits the TemBreak 2 Lite S160-SCJ (160 A frame) together with the E250-SJ, S250-SJ and S250-SN (250 A frame). Auxiliary and alarm switches can share the breaker.
