The MGN25149 is a Schneider Electric C60H miniature circuit breaker from the Multi9 range, configured as a 4-pole unit with a D-curve trip characteristic and a 40 A rated current at 50 °C per IEC 60947-2. The 40 A rating at 50 °C means it carries full current in a warm panel; no derate needed until ambient exceeds that threshold. Breaking capacity is rated at 15 kA Icu at 415 V AC and 30 kA Icu at 240 V AC, both phase-to-phase per IEC 60947-2.
The part carries IEC 60947-2 certification as its primary standard. No separate UL or CSA listing appears in the record; if the application requires a UL 489 listing for a North American panel, verify the specific file number before specifying. The Multi9 range includes UL-listed variants, but this order code should be checked against the project's approval list.
Integration
The 4-pole body occupies 8 x 9 mm pitches (72 mm wide), which is the standard footprint for a 4P MCB in the Multi9 family. Tunnel-type terminals accept 1.5 to 35 mm² conductor — solid, stranded, or flexible with ferrule — and the power-circuit tightening torque is 3.5 N·m. Strip length is 14 mm. The IP20 finger-safe enclosure is standard for panel-mount distribution boards; no additional shrouding needed inside a closed cabinet. The breaker provides ON/OFF indication via a toggle and a contact position indicator, which helps during commissioning and fault-finding. Earth-leakage protection requires a separate block — this is the thermal-magnetic MCB only, not an RCBO. For circuits requiring ground-fault protection, pair it with a compatible vigi add-on block from the same range.
