What is a Circuit Protection device?

A circuit protection device is a fail-safe device that originates a disruption in an electrical circuit when it recognizes an excess and unsafe power load in a circuit. The main aims of circuit protection are to localise and isolate the situation or fault and avert and minimize any unnecessary power loss.
