Product details

What this MCB delivers for the panel

The MGN25129 is a C60H miniature circuit breaker from the Multi9 range — a 3-pole, D-curve unit rated 10 A at 50 °C per EN/IEC 60947-2. Breaking capacity is 30 kA Icu at 240 VAC phase-to-phase, stepping down to 15 kA at 415 VAC and 10 kA at 440 VAC — enough headroom for most distribution panels where the upstream transformer or feeder can deliver that fault current. The 3-pole configuration with separate earth-leakage block option means it can serve as the main branch protection in a sub-distribution board, leaving the RCD function to a companion module.

Depth is 73 mm, height 81 mm — fits standard distribution enclosures with adequate wiring space. Tightening torque for power circuit terminals is 2 N·m; strip length 14 mm. No derating needed in typical panel conditions. Ambient operating range -30…70 °C covers most indoor and sheltered outdoor cabinets.

Frequently asked questions

What is the breaking capacity of MGN25129?

The MGN25129 is rated 30 kA Icu at 240 VAC phase-to-phase, 15 kA at 415 VAC, and 10 kA at 440 VAC, all per EN/IEC 60947-2. The service breaking capacity (Ics) is 50 % of those values.

What does the D-curve mean on this MCB?

The D-curve sets the magnetic trip threshold at 12 x In (±20 %), so the breaker tolerates high inrush currents typical of motor loads, small transformers, and discharge lighting without tripping on startup.

What compliance standards does MGN25129 meet?

The MGN25129 is designed and tested to EN/IEC 60947-2 for miniature circuit breakers, with pollution degree 3 and IP20 protection. It carries suitability for isolation and a contact position indicator per that standard.
