MGN60527 C60N — 40 A D Curve MCB, 2-Pole
The MGN60527 is a C60N miniature circuit breaker from the Multi9 range, rated 40 A at 50 °C with a D tripping curve, 2 poles, and a 20 kA Icu breaking capacity at 240 V AC phase-to-phase. Breaking capacity is 20 kA Icu at 240 V AC, 10 kA at 415 V, and 6 kA at 440 V, all per EN/IEC 60947-2. The service breaking capacity (Ics) is 75 % of Icu at each voltage level — 15 kA at 240 V, 7.5 kA at 415 V, 4.5 kA at 440 V — which tells you the breaker can be reclosed after clearing a fault at those levels without immediate replacement. Rated operational voltage is 440 V AC, and the unit is suitability for isolation certified per the same standard. The contact position indicator gives a visual ON/OFF confirmation at the toggle.
Depth is 73 mm, height 81 mm. Tightening torque for the power circuit is 3.5 N·m. Pollution degree 3 per EN/IEC 60947-2 — suitable for industrial enclosures where conductive pollution may occur. IP20 finger-safe protection on the front face. Earth-leakage protection requires a separate block (not integrated). The breaker itself provides thermal-magnetic overcurrent protection on both poles.
