The MGN60904 is a 4-pole C60N miniature circuit-breaker from the Multi9 range, rated 4 A with a C trip curve. Breaking capacity is 20 kA Icu at 240 V AC phase-to-phase, 10 kA at 415 V AC, and 6 kA at 440 V AC, all per EN/IEC 60947-2. Rated operational voltage is 440 V AC 50/60 Hz, so it covers standard 400/415 V three-phase panels. The thermal-magnetic trip unit handles overloads thermally and short-circuits magnetically — no electronics to fail.
Mounting and integration — DIN rail, 8-pitch footprint
The 4-pole body takes 8 x 9 mm pitches (72 mm wide), so plan for 72 mm of rail space plus finger-duct clearance on each side. Strip length 14 mm. IP20 rated — suitable for enclosed panel use only, not washdown or outdoor. Ambient operating range -30…70 °C, storage -40…80 °C.
