The MGN60549 is a Schneider Electric C60N miniature circuit breaker from the Multi9 range — a 4-pole, D-curve device rated 16 A at 50 °C per EN/IEC 60947-2. Breaking capacity reaches 20 kA Icu at 240 V AC phase-to-phase, 10 kA at 415 V, and 6 kA at 440 V — the 20 kA figure is the one that matters for most panel-fed distribution boards where the prospective fault current sits in that range.
IP20 finger-safe terminals are standard for enclosed panel use.
Suitability for isolation is confirmed. The thermal-magnetic trip unit provides overload protection via the bimetal element and short-circuit protection via the solenoid — no separate earth-leakage module inside, though a separate block can be added. Operating temperature range is -30…70 °C, storage -40…80 °C.
