What is an Overload Relay? Why is it essential for industries?

An overload relay is a protective device used to protect motors by disconnecting them whenever they are drawing too much current, overheated, or running at low voltage continuously for long hours. Industries use overload relays to avoid damaging the motors, and in case they get destroyed, the industry will face a huge blackout which can lead to the stoppage of production, equipment damage, and heavy financial losses which affect a lot of employees working in that organization.

Types of overload relay

There are two types of relays: thermal overload relay and electronic overload relay. The thermal overload relay works on the principle of temperature rise by current, whereas an electronic overload relay uses microprocessor technology to identify overcurrent or overheating.

Working of Thermal Overload Relay

Thermal overload relay uses the principle of thermal effects by current. It consists of a bimetallic strip which gets heated by the motor current in case of overload. As a result, the bimetallic strip bends which makes the relay trip and de-circuit the motor from mains. This prevents damage to the motor.

Some distinguishing characteristics of electronic overload relays

High degree of accuracy, higher rate of operations

What is the price range of Overload Relay?

Based on the type, features, and brand, the price range may differ vastly. Generally, the overload range is lesser for thermal overload relays due to their simplicity, whereas it may be on the higher end for an electronic relay because of the advanced options to protect the motor.

Any reliable option to buy these relays with some cost benefits?

Industrybuying is a self-esteemed platform for a wide variety of overload relays including thermal overload and electronic overload relays. It provides up to 28% GST benefits which can be one of the economical options for the industries.

Can good quality overload relay be counted as a valuable investment for the industries?

Yes, a good quality overload relay such as thermal overload relay or electronic overload relay is a good buying option for the industries in terms of production efficiency and potential loss in case of motor burnouts.
