Product details

The MGP1252L1N is a Schneider Electric PowerPacT 4 molded case circuit breaker (MCCB) with 1P+N configuration, rated 125 A at 40 °C for 230 V AC 50/60 Hz distribution. It carries a 25 kA Icu and Ics at 415 V AC, meeting BS EN 60947-2 for isolation suitability.

That's a strong short-circuit rating for a 1P+N distribution breaker in a 230 V panel. Mounts to a backplate, horizontal or vertical, with 2 module spaces (35 mm per module). The toggle control and panel-mounted design make it a straightforward swap in a distribution board — no DIN-rail adapter needed, just the backplate screws.

Frequently asked questions

What is MGP1252L1N's short-circuit breaking capacity?

The MGP1252L1N has a 25 kA Icu and 25 kA Ics at 415 V AC 50/60 Hz. Both ratings are equal, so the breaker can clear a fault and be reused without derating.

What standards does the MGP1252L1N comply with?

The MGP1252L1N complies with BS EN 60947-2 and is suitable for isolation per that standard.

Where can I buy the MGP1252L1N?

The MGP1252L1N is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock or lead-time figures are published here.
