We will explain the concept of self-holding relays, how they function within a holding circuit, and the importance of auxiliary contacts in the setup.

Learn about the different motor control techniques utilized in DOL starters and the significance of the self-holding contactor circuit in maintaining operations without continuous input. We will also cover practical aspects, including how to wire a self-holding relay and auxiliary contactor wiring, providing you with the knowledge to implement these systems effectively.

Whether you're an engineer, technician, or simply interested in automation techniques, this video will enhance your understanding of control systems, relay circuits, and the specifications of contactors. Discover how self-latch relays contribute to efficient motor automation and improve your skills in industrial control.

Join us as we break down the intricacies of self-holding contractors, their applications in motor starters, and how they streamline processes in various industrial settings. Don't miss out on this essential guide to mastering self-holding relays and contactors!

Let's say you want to control your Three or single-phase motor with a self-holding circuit.
First, you will need the following

(1) CONTACTOR (4 poles) or with NO auxiliary
(2) STOP AND START PUSHBUTTONS
(3) AUTO CABLES (for connection)

First, make sure you follow the CIRCUIT as per the reference in the video.
