Description

The Duke 502812 Circuit Breaker/Switch is an electrical switch that is used to control the flow of power in an appliance by automatically disconnecting the power once the current surpasses 20 amps to prevent overloading of components and wiring. Its 2-pole design can disconnect both lines of 120/240V circuits at the same time in case of faults. The breaker is mounted in the electrical panel/junction box of the oven and directly linked to the power supply of the unit and internal wiring. It works automatically to close and open the circuit when necessary to keep safe in normal cooking cycles.
