The MGP0252L12 is a 2-pole PowerPacT 4 molded case circuit breaker from Schneider Electric, rated 25 A at 40 °C with a thermal-magnetic TM-D trip unit providing LI protection (overload and short-circuit).
Schneider has marked the MGP0252L12 as obsolete.
Key Ratings & Fit
That's useful for high-fault panels where you can't afford a blown fuse or a breaker that needs replacement after a fault. The thermal-magnetic trip is fixed at 25 A (no adjustment range), so it's a straight replacement for a distribution circuit that doesn't need field-adjustable settings. Panel-mounted, backplate support, and rated for horizontal or vertical orientation — fits standard enclosure layouts.
