The MGP1602L23 is a 2-pole molded case circuit breaker from the PowerPacT 4 range, rated 160 A at 40 °C with a thermal-magnetic TM-D trip unit providing LI protection — thermal overload (L) and magnetic short-circuit (I). It carries a 25 kA Icu and Ics at 415 V AC 50/60 Hz, which means it can safely interrupt fault currents up to that level without upstream cascading, and it is Category A (no intentional short-time delay) per BS EN 60947-2.
Deployment context
Panel-mounted on a backplate, this breaker accepts horizontal or vertical orientation and occupies a 2-module (35 mm per module) footprint. It connects L2-L3 phase-to-phase, so it is wired as a single-phase or phase-to-phase load breaker in a 3-phase distribution board — not a full 3-pole main. The toggle control and suitability for isolation (BS EN 60947-2) make it straightforward for a panel builder to use as a disconnecting means for downstream equipment.
