The MGN25089 is a Schneider Electric C60H miniature circuit breaker from the Multi9 range, rated 32 A at 50 °C with a D trip curve. It protects a single pole (1P) in AC distribution networks at 240 V phase-to-neutral. The thermal-magnetic trip unit handles overloads via the bimetal strip and short-circuits via the solenoid. Breaking capacity is 15 kA Icu at 240 V AC and 4 kA Icu at 415 V AC, both per EN/IEC 60947-2. The service breaking capacity (Ics) is 50 % of Icu: 7.5 kA at 240 V, 2 kA at 415 V. That means after clearing a fault at these levels the breaker remains functional, not just safe.
Depth is 73 mm, height 81 mm. Tunnel terminals accept 1.5 to 35 mm² rigid or flexible wire; tightening torque is 3.5 N·m. Strip length 14 mm. IP20 finger protection on the front.
Suitable for isolation (marked with the open-contact indicator). The toggle provides local ON/OFF indication. Earth-leakage protection requires a separate block — this is the MCB only. Electrical endurance is 10,000 cycles, mechanical 20,000 cycles. Utilisation category A (non-delayed short-circuit release).
