The MGP2504X is a 4-pole (3P+N) PowerPacT 4 molded case circuit breaker rated 250 A at 40 °C, with a TM-D thermal-magnetic trip unit providing LI protection — thermal overload (L) and magnetic short-circuit (I). It is designed for distribution in 250 A or 400/630 A panelboards, panel-mounted on a backplate, and can be installed horizontally or vertically.
Breaking capacity and isolation
Rated ultimate short-circuit breaking capacity (Icu) is 36 kA at 415 V AC 50/60 Hz, with the same 36 kA service breaking capacity (Ics). The breaker is suitable for isolation per BS EN 60947-2, meaning it provides a visible disconnect gap when open.
Lifecycle reality — obsolete, not orphaned
Schneider Electric lists the MGP2504X as obsolete. No official successor order code is published in the available records.
Durability and adjustment range
Thermal protection adjustment covers 175 to 250 A. Electrical durability is rated at 20,000 cycles at 440 V at rated current, and 10,000 cycles at 440 V at twice rated current. The toggle control is manual; no earth-leakage protection is integrated.
