Breaking capacity is 121 kA at 240 V AC, dropping to 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V — that covers most industrial fault-current scenarios without needing a current-limiting upstream device.
Above that, it derates gradually: 39 A at 55 °C and 60 °C, 38 A at 65 °C, and 37 A at 70 °C.
The breaker measures 130 mm high, 101.6 mm wide, and 70 mm deep — a standard 4-pole MCCB footprint.
At 240 V it's 121 kA; at 415 V it's 75.6 kA; at 440 V it's 52.5 kA; at 500 V and 690 V it's 11.9 kA. That's a strong SCCR for most industrial distribution panels.
