Four poles, line-protection design, with ground-fault monitoring via summation current formation on L + N. Breaking capacity hits 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. The 86 mm depth and 140 mm width fit standard panel layouts; the 181 mm height clears most enclosure gland plates without a riser.
Ground-fault monitoring detail
The ground-fault monitoring uses summation current formation on L + N, meaning it compares the vector sum of phase and neutral currents to detect leakage. No separate measurement function or undervoltage release is built in — this is a straight line-protection MCCB with integrated GF protection, not a multi-function trip unit.
