Switch disconnector, 160 A, with shunt trip
It's designed for isolation and switching of loads up to 690 V AC or 500 V DC, without overload or short-circuit protection — that's the disconnector role, not a breaker. The integrated shunt trip release (STL) operates on 110-127 V DC or AC, letting you remote-trip the device from a control system or emergency-stop circuit.
The 160 A continuous rating (Iu) sets the maximum load it can carry without exceeding temperature limits — sized for a feeder or large motor branch circuit. The 690 V AC / 500 V DC maximum operational voltage covers standard 400 V three-phase panels and 480 V industrial supplies, with headroom for 690 V applications.
