Specification and compliance summary
Rated at 10 A at 50 °C per EN/IEC 60947-2, it provides thermal-magnetic overcurrent protection for distribution circuits where high inrush currents — typical of motor loads or transformer primaries — must be accommodated without nuisance tripping. The D-curve magnetic trip threshold is 12 x In (±20 %), meaning the instantaneous trip initiates between 9.6 and 14.4 times the rated current. This suits loads with moderate inrush, such as small motors, solenoid banks, or control transformers, where a B- or C-curve breaker would trip on energisation. Breaking capacity is rated at 20 kA Icu at 240 V AC phase-to-phase, 10 kA Icu at 415 V AC, and 6 kA Icu at 440 V AC, all conforming to 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, and 4.5 kA at 440 V — providing adequate fault-clearing headroom for most commercial and light industrial distribution boards.
The breaker mounts on a 35 mm symmetrical DIN rail per EN/IEC 60715, occupying 8 x 9 mm pitches (72 mm width) in the enclosure. The 4-pole format with separate earth-leakage block provision allows compact assembly in distribution boards where space is at a premium. Tunnel-type terminals accept 1–25 mm² conductors (solid, flexible with or without ferrule). The toggle actuator provides local ON/OFF indication with a contact position indicator for positive isolation verification.
The MGN60548 is classified as current-production (active lifecycle stage). Compliance documentation per EN/IEC 60947-2 is available; the breaker carries suitability for isolation marking and pollution degree 3 rating for use in typical industrial environments.
