It is rated for isolation and falls under utilisation category A.
The F breaking-capacity code delivers 70 kA Icu at 220/240 V AC and 36 kA Icu at 380/400 V AC, both per EN/IEC 60947-2. For a 250 A frame this means it can sit upstream of a 400 V distribution board with enough headroom to clear a bolted fault without cascading — the SCCR of the downstream panel is limited by the breaker's rating, not the other way around. The 70 kA at 240 V also makes it a clean fit for North American 240/120 V split-phase services where fault currents can hit 65 kA.
Fixed mount on a backplate with front-facing line and load connections. Neutral is on the left. IK07 impact rating means it survives a tool bump in a crowded panel.
Durability and thermal limits
Rated for 20,000 electrical cycles at 415 V at In/2 per EN/IEC 60947-2, and 20,000 mechanical cycles. The integral instantaneous magnetic trip is set at 2500 A. Long-time pickup is fixed at 1 In. Storage temperature range -50 to 85 °C.
