Relays and contactors are electromagnetically operated switches used to control high-power circuits with low-power signals.
Critical protective devices designed to cut power if a motor draws excessive current for too long. Return to their normal state as soon as they are released
The simplest method to start a 3-phase induction motor. It connects the motor terminals directly to the power supply through a contactor.
