MINIATURE CIRCUIT-BREAKER S503-K0.21

The S500 high perfomance circuit breaker fullfils he requirement of larger short-circuit currents, thus in turn placing heavy demands on protective sitchgear reagrding safety, reliability and switching capacities. It is equipped with thermal and / or electromagentic release to protect circuits, motors, switchgear and systems from the effect of overload and short cicruit currents.
