Product details

The MGN60644 is a Schneider Electric C60H miniature circuit breaker from the Multi9 range, rated 40 A at 50 °C per EN/IEC 60947-2 with a C-curve trip characteristic.

The C-curve magnetic trip fires at 5 to 10 times In (8.5 x In +/- 20 % per the spec), which suits moderate inrush loads like motor starters, small transformers, and lighting banks — not the high-inrush of large drives or the purely resistive load of a heater bank. The thermal-magnetic trip unit combines a bimetal for overload protection and a solenoid for short-circuit; no electronics to fail or drift.

The 54 mm width (6 x 9 mm pitches) and 73 mm depth fit the Multi9 modular footprint; comb busbars and distribution blocks are compatible top or bottom. Tunnel-type terminals accept 1.5 to 35 mm² flexible or rigid wire; strip length 14 mm, tighten to 3.5 N·m.

Frequently asked questions
