Product details

The Schneider Electric MGP1252L12 is a PowerPacT 4 molded case circuit breaker (MCCB) with a 2-pole configuration (-L2 phases), rated 125 A at 40 °C and 415 V AC 50/60 Hz. It uses a thermal-magnetic TM-D trip unit providing LI protection — thermal for overload, magnetic for short-circuit. The BS EN 60947-2 standard certifies its performance for industrial distribution panels.

Panel-mounted on a backplate, accepts horizontal or vertical orientation. The 2-module (35 mm per module) footprint fits standard DIN-rail-mount enclosures, though the breaker itself is screw-fixed to the backplate, not snap-on. Toggle control for manual on/off and trip reset.

Rated insulation voltage 750 V and impulse withstand 8 kV give headroom for distribution panels with transient surges.

Frequently asked questions

What is the breaking capacity of MGP1252L12?

The MGP1252L12 has a 25 kA Icu and Ics at 415 V AC 50/60 Hz, meaning it can safely interrupt a fault up to 25 kA without damage and be reclosed after a fault at that level.

What standard does MGP1252L12 comply with?

The MGP1252L12 is certified to BS EN 60947-2, the standard for molded case circuit breakers used in industrial distribution.

Where can I buy MGP1252L12?

As an obsolete part, MGP1252L12 is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no standard stock or lead time is published.
