Product details

The Siemens 5SL4303-6CC is a 3-pole miniature circuit breaker from the SENTRON 5SL4 family, rated 3 A with a B-curve trip characteristic. It interrupts fault currents up to 10 kA at 400 V AC — that 10 kA rating means it handles the full prospective short-circuit current on most commercial and light-industrial distribution boards without needing an upstream current-limiting device.

RoHS compliant since 01 June 2013. REACH candidate-list information is available on request.
