The MGN60872 is a Schneider Electric C60N miniature circuit-breaker from the Multi9 range — 1-pole, C-curve, rated 40 A at 50 °C per EN/IEC 60947-2.
Thermal-magnetic trip with a C-curve: the thermal bimetal protects against sustained overloads, the magnetic coil clears short-circuits. At 8.5 x In (340 A instantaneous pickup for this 40 A unit), it avoids nuisance tripping on capacitor-switching or motor-start transients while still meeting IEC 60947-2 Category A coordination requirements.
Panel integration
Single-pole width is 18 mm (2 x 9 mm pitches), so it occupies one module position in a distribution board. Tunnel-type terminals accept 1.5 to 35 mm² flexible or rigid copper — no need for pin ferrules on the larger sizes, though 35 mm² stranded benefits from a ferrule to avoid splaying under the screw. IP20 finger-safe terminals only — this is for enclosed panels, not open-wall mounting.
Approvals and documentation
Certified to EN/IEC 60947-2, pollution degree 3, suitability for isolation marked on the device. The toggle provides local ON/OFF indication with a contact position indicator that shows true contact state, not just handle position — a safety requirement for isolation switching. The C60N family carries CE and UKCA marking for European markets; separate earth-leakage protection block available as an add-on. RoHS and REACH compliance declarations are standard from Schneider Electric for this production code.
