Relays (Overload / Auxiliary / Protection)
Relays are electromechanical or electronic switching devices used to control electrical circuits by opening or closing contacts in response to an input signal. Overload relays protect motors and circuits from excessive current, auxiliary relays provide signal and control functions, and protection relays safeguard electrical systems from faults like overcurrent, undervoltage, and short circuits. These relays are critical components in industrial automation, motor control, and electrical protection systems.
