Duke 502805 Switch Circuit Breaker 2-Pole 20A

The Duke 502805 Switch Circuit Breaker 20 Amps 2-Pole is an electrical protection and switching part that manages power distribution across two connected circuits. It combines manual power control with overload protection allowing electrical current to pass under normal conditions while interrupting the circuit when current levels exceed the rated capacity. The internal trip mechanism responds to an excessive electrical load by separating the contacts to stop power flow and protect connected parts from damage. Mounted within an electrical panel or control compartment, it provides a resettable means of restoring circuit continuity after the source of the overload has been addressed.
