Product details

Its interrupting capacity reaches 220 kA at 240 V AC, 154 kA at 415 V and 440 V, 121 kA at 500 V, and 17 kA at 690 V — covering high-fault installations where upstream breakers must clear severe short circuits without cascading failure.

Ratings and thermal performance

Rated current holds at 400 A from 40 °C through 50 °C ambient, then derates to 392 A at 55 °C, 384 A at 60 °C, 376 A at 65 °C, and 367 A at 70 °C. This derating curve is essential for panel builders calculating fill factor and ventilation — at 70 °C the breaker still carries 367 A continuous without nuisance tripping.

The trip indicator (visible flag) and auxiliary switch wiring points are accessible with the breaker installed.
