Product details

The MGN25143 is a 4-pole C60H miniature circuit breaker from the Multi9 range, rated 10 A with a D tripping curve. Breaking capacity reaches 30 kA Icu at 240 V AC phase-to-phase, 15 kA at 415 V, and 10 kA at 440 V, all per EN/IEC 60947-2.

The 4-pole body occupies 8 module pitches of 9 mm each, so plan for 72 mm of panel width. Strip 14 mm of insulation.

Environmental and isolation

IP20 finger-safe terminals. Suitability for isolation is confirmed per EN/IEC 60947-2, with a visible contact position indicator.

Listed as current production. The C60H platform is a mature, widely stocked line in the Multi9 family.

Frequently asked questions

What is the breaking capacity of MGN25143?

30 kA Icu at 240 V AC phase-to-phase, 15 kA at 415 V, and 10 kA at 440 V, all per EN/IEC 60947-2. The service breaking capacity Ics is 50 % of Icu at each voltage.

What does the D-curve mean on this breaker?

The D-curve sets the magnetic trip threshold at 12 x In (±20 %), so the breaker tolerates high inrush currents from motor loads, transformers, or welding equipment without tripping on startup.

Where can I buy MGN25143?
