Circuit Breakers, Switches & Terminal Blocks
Circuit Breakers, Switches & Terminal Blocks
Switches are typically used for turning power on and off to particular devices. Circuit Breakers, on the other hand, serve the purpose of circuit protection in the event of overcurrent or electric leakage. Terminal blocks consist of multiple terminals for connecting, joining or branching the flow of electric current.
