To prevent this, it is important to wire the starter so the current is balanced between the contacts on the overload relay. Single-Phase Motor, 3 Phase Contactor: How It’s Done. Here again is our picture of the 3-pole motor starter. The contactor is on top and the overload relay is attached directly to it on bottom. You see 4 terminals ...

Star Delta Starter (Y – Δ) is a common type of three phase (3 phase) induction motor starters generally used in low starting torque motors. Motor Starters are types switches (either electromechanical or solid state) that are designed to start and stop the motors by providing the necessary power to the motor and preventing the motor to draw excess current.
