The MGN25113 is a C60H miniature circuit-breaker from the Multi9 range, rated 4 A at 50 °C with a D tripping curve. Rated 30 kA Icu at 240 V AC phase-to-phase, it clears faults up to that level under EN/IEC 60947-2, which means it can be used as the main branch breaker in a sub-panel with a high available fault current.
Where it goes in the panel
The 36 mm width (4 x 9 mm pitches) means it occupies two adjacent module spaces, so plan the DIN rail fill accordingly. Tunnel-type terminals accept 1 to 25 mm² rigid or flexible wire; strip 14 mm and torque to 2 N·m. The toggle actuator gives a clear ON/OFF indication, and the contact position indicator confirms isolation status — useful during lockout/tagout.
Compliance and approvals
The separate earth-leakage block option (Vigi C60) lets you add residual-current protection without swapping the breaker.
