Breaking capacity — the real-world fault-handling range
Breaking capacity drops sharply as system voltage rises: 220 kA at 240 V, 154 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V. At 415 V it still clears 154 kA — that is well above typical industrial service-entrance fault levels — so this breaker suits high-fault panels where a standard 50 kA or 65 kA MCCB would not hold coordination. The 36 kA at 440 V is still a strong figure for 440 V distribution.
Thermal derating — what 250 A means at panel temperature
Above 55 °C it derates: 243.3 A at 55 °C, 236.5 A at 60 °C, 229 A at 65 °C, 223 A at 70 °C.
Auxiliaries and accessories fitted
The shunt trip order code is 3VA9688-0BL32 — if you need a spare or a replacement, that is the sub-component to order.
