​Altech 2D15UR Circuit Breaker



What is a Circuit Breaker?

A circuit breaker is an automatically operated electricalswitch designed to protect an electrical circuit from damage caused by overcurrent/overload orshort circuit. Its basic function is to interrupt current flow after protective relaysdetect a fault. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation.

Generally used in a loadcenter, panelboard, or similar device, industrial miniature circuit breakers are a specific type of circuit breaker, used to switch and protect the lowest common distribution voltage in an electrical system.
