Did you know how to convert 3-phase thermal relay into 1 phase? In this article, Hao Phuong will help you on how to convert 3-phase thermal relay into 1 phase through a diagram.
What is the thermal relay?
Thermal relay is a protective device from heat through bimetal bars. Thermal relays are usually designed with 3 independent poles which are 3 bimetallic bars.
These three bimetallic rods are designed to be used for 3-phase current. So when we use it for 1-phase (2-wire) current, how do we use it to safely use the motor.

The wiring diagram converts 3-phase thermal relay into 1 phase
The following is a wiring diagram that converts 3-phase thermal relay into 1 phase. You can wire in 1 of 2 diagrams below:
With the above diagram, you can use a thermal relay for electrical circuits using a single-phase current. Hope this article will help you use the efficient and safe thermal relay.
