It carries a 440 kA interrupting capacity at 240 V, derating to 330 kA at 415 V and 52.5 kA at 690 V — meaning it can safely clear high-fault currents across common industrial voltage levels without upstream coordination issues.
Ground-fault and thermal performance
Ground-fault monitoring uses summation current formation on L+N conductors — it detects imbalance between line and neutral, not just residual current. This is common on solidly-grounded TN systems where you want to catch leakage before it becomes a fault. Power loss is minimal at 3 W maximum.
Dimensions are 181 mm high by 140 mm wide by 86 mm deep (7.13 × 5.51 × 3.39 in). The 4-pole width matches the typical 140 mm form factor for 63 A MCCBs in distribution panels. No undervoltage release and no communication function — it is a straight thermal-magnetic line protection breaker with ground-fault summation.
