CUDIS MC140B 40A SP 6KA TYPE B MCB

The CUDIS MC140B is a single-pole miniature circuit breaker designed to protect final circuits against overloads and short circuits. Rated at 40A with a Type B tripping characteristic, it is suited to general-purpose lighting and socket circuits where inrush currents are low. The unit provides a 6kA short-circuit breaking capacity, mounts on standard DIN rail, and features a reliable thermal-magnetic mechanism with clear ON/OFF indication for easy resetting after a fault.
