The MGN25134 is a C60H miniature circuit-breaker from the Multi9 range, rated 32 A at 50 °C with a D tripping curve. The 30 kA Icu at 240 V AC (phase-to-phase) tells you the breaker can safely interrupt a fault up to that level; at 415 V the breaking capacity drops to 15 kA Icu, and at 440 V to 10 kA Icu.
Deployment context
The IP20 rating means it's intended for dry indoor enclosures — not washdown or outdoor exposure. Pollution degree 3 (conforming to the same standard) suits it for industrial environments where conductive pollution may occur, but the enclosure must keep it dry.
