Breaking capacity — the number that matters for fault duty
This breaker carries a breaking capacity of 121 kA at 240 V, 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.
Thermal derating — real-world current capacity
The 32 A rating holds steady up to 50 °C ambient. That's a mild slope — you don't lose much headroom even in a hot enclosure, but if you're packing breakers tight in a panel above 50 °C, factor in that 1–2 A drop per circuit.
Built-in accessories and panel fit
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep, so it fits a standard 3-pole MCCB slot in a SENTRON or generic distribution panel without surprises.
