Product details

Interrupting capacity and coordination

The Siemens 5SJ4203-7HG41 is a 2-pole SENTRON miniature circuit breaker with a C-curve tripping characteristic, rated 10 kA interrupting capacity per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC.

Voltage ratings and DC capability

Rated 400 V AC and 60 V DC maximum. The DC rating is the limiting factor for control-circuit applications — if you're switching a 125 V DC bus this breaker won't hold the arc. Stick to 60 V DC or below for DC-side use.
