The MGP0251L3 is a 1-pole molded case circuit breaker from the Schneider Electric PowerPacT 4 range, rated 25 A at 40 °C for 230 V AC 50/60 Hz distribution circuits. The breaker is Category A (no intentional short-time delay), suited for downstream branch protection where selectivity is achieved by current magnitude rather than time delay. Rated insulation voltage is 750 V, impulse withstand 8 kV, and the breaker is suitable for isolation per BS EN 60947-2.
Panel-mounted via backplate, occupying a single 35 mm module width. Accepts horizontal or vertical orientation. The toggle control provides manual on/off and trip indication — no rotary handle or extended shaft. Phase connection is L3 (line side), consistent with 1-pole wiring in a single-phase or line-to-neutral distribution scheme.
Durability and compliance
Rated for 20,000 mechanical operations and 20,000 electrical cycles at rated current (In), halving to 10,000 cycles at 2× In. Standards compliance is BS EN 60947-2, the UK adoption of the IEC 60947-2 low-voltage switchgear standard. No earth-leakage protection is integrated.
