The Wico 1P/C40A/4.5kA miniature circuit breaker is designed to protect low-voltage electrical circuits from overload and short-circuit conditions, and to perform occasional manual switching. It carries a rated current of 40A with a short-circuit breaking capacity of 4.5kA, using a type C tripping curve suited to resistive and inductive loads with moderate inrush currents.

The device mounts on a standard 35mm DIN rail and is rated for indoor installation at IP20. It is manufactured to EU origin standards and complies with EN 60898-1 and CE marking requirements.
