The MGP1602L31 is a 2-pole PowerPacT 4 molded case circuit breaker from Schneider Electric, rated 160 A at 40 °C with a 25 kA Icu/Ics breaking capacity at 415 V AC. This is a Category A breaker (no intentional short-time delay), panel-mounted, with toggle control and suitability for isolation per BS EN 60947-2.
It occupies a 2-module (35 mm per module) footprint on the panel. Phase connection is L3-. The 750 V rated insulation voltage and 8 kV impulse withstand voltage align with standard distribution panel clearances. At 160 A continuous, plan for lug or busbar sizing that matches the 40 °C base rating — no derating needed at that ambient, but a warmer enclosure will require a downward adjustment.
The breaker is rated for 20,000 mechanical cycles and 20,000 electrical cycles at rated current (277 V In/2), with 10,000 cycles at full 277 V. No earth-leakage protection is integrated. The toggle control gives a clear visual indication of trip status — useful for a field-service tech fault-isolating a downstream short.
