How it works?

Working principle and characteristics of the relay
It is actually an "automatic switch" that uses a smaller current to control a larger current. Relay plays the role of automatic adjustment, safety protection, and conversion circuits in the circuit.

How Do Fuses Work?
They consist of a fusible element that melts or vaporizes when the current exceeds the fuse rating, breaking the electrical connection and thus safeguarding electrical devices.
