Abstract
A programming device and a programmable circuit breaker are provided for switching off electric current. The circuit breaker comprises a mechanism (208) to monitor the strength of electric current in a switching mechanism (210) to switch off the passage of the electric current through the circuit breaker. To enable versatile timing of electric appliances, the circuit breaker includes a device (218) to store one or more desired time periods, an interface (220) to a separate program device of the time periods, and a control device (216, 220) to control the switching element (210) on the basis of the time period stored.
