The MGP1601L2 is a 1-pole molded case circuit breaker from the Schneider Electric PowerPacT 4 range, rated 160 A at 40 °C with a thermal-magnetic LI trip unit (TM-D) that provides overload (thermal) and short-circuit (magnetic) protection for distribution circuits. Rated operational voltage is 230 V AC 50/60 Hz, with a rated insulation voltage of 750 V and impulse withstand voltage of 8 kV — the 230 V rating matches standard single-phase residential and light commercial panel voltages, while the 750 V insulation headroom covers the backplane wiring stress in a panel environment. Breaking capacity is 25 kA Icu and 25 kA Ics at 230 V AC, both equal. The breaker is panel-mounted (backplate), accepts horizontal or vertical orientation, and occupies a single 35 mm module width — the 1P form factor and narrow footprint suit it for tight single-phase subfeeds or as a main breaker in a small panel.
The part is obsolete.
The MGP1601L2 is designed and tested to BS EN 60947-2, the standard for low-voltage switchgear and controlgear circuit breakers. It is suitable for isolation per that standard, meaning it can be used as a disconnecting means in a circuit. Control is via a toggle mechanism. No earth-leakage protection is integrated — that function would need an external RCD or RCBO if required.
