ON/OFF 3-phase motor Using 8-PIN Relay and contactor | ON-OFF motor control circuit.
Three-phase motors are widely used in various industrial applications due to their efficiency and reliability. Properly controlling the operation of these motors is crucial for the smooth functioning of industrial processes. As there are multiple ways to control a single phase and three-phase motor, like DOL starter, Star-delta starter, VFD and PLC based controlling methods, but in this tutorial, we are going to learn the simple way to Start and Stop a 3-Phase motor based on a combination of an 8-PIN relay and a Direct-On-Line (DOL) starter.
In this article, we will show how to control the ON/OFF operation of a Three-phase motor using both an 8-PIN relay and a DOL starter with wiring, power and control diagrams.
Components Required:
The following components and devices are required to make an ON/OFF control circuit for controlling the Three-phase motor based on an 8-PIN relay and a DOL starter:
1-Three-Phase Motor.
2-8-PIN PLA Relay.
3-DOL Starter (based on Contactor & Thermal Overload Relay).
4-2-MCB and 3-P MCCB.
5-Control Switches (Start “NO” and Stop “NC”).
6-Single Phase & Three Phase Supply.
7-Wires & Cables.
