Product details

Its interrupting capacity is 220 kA at 240 V AC, 154 kA at 415 V, and still 17 kA at 690 V — meaning it can clear high-fault currents on the secondary side of a large transformer without cascading upstream. At 40 °C ambient the breaker carries the full 250 A without derating; at 55 °C it still holds 243 A, and at 70 °C it is rated 223 A.

Mounting dimensions and panel integration

The 4-pole width (140 mm) matches the standard SENTRON 3VA frame footprint for a 250 A unit — it occupies the same DIN-rail or screw-mount positions as other 3VA1 breakers of the same rating.

Frequently asked questions
