Overload Relays

Jay Controls Automations Pvt Ltd is one of the dealers for switchgears & capacitors in India which supplies the qualitative and reliable electric products in the market. An overload relay is an electrical device that is used to protect electric motors from overloads. Overloads can occur when a motor is asked to draw more current than it is designed to handle. This can cause the motor to overheat and damage the windings. We provide the product range which includes contactors, Switches, switch gears, Over Load Relays, Air Circuit Breakers, Load Break Switches, Fuses, Digital Soft Starters, Electric Timers, Limit Switches and Safety Relays etc.

What is Power Contactor?

Overload relays work by sensing the current flowing through the motor. When the current exceeds a predetermined value, the overload relay will trip and open the circuit, disconnecting the motor from the power supply. This prevents the motor from overheating and damaging the windings.

There are two main types of overload relays: thermal overload relays and electronic overload relays.

Thermal overload relays use a bimetallic strip to sense the current flowing through the motor. When the current exceeds a predetermined value, the bimetallic strip will bend and open the circuit, disconnecting the motor from the power supply.

Electronic overload relays use a sensor to measure the current flowing through the motor. When the current exceeds a predetermined value, the sensor will send a signal to the overload relay, which will then open the circuit, disconnecting the motor from the power supply.

Overload relays are an important safety device that can help to prevent damage to electric motors. They are typically used in conjunction with motor starters to provide a complete motor protection solution.

Here are some of the benefits of using overload relays :
  • Overload relays help to prevent motors from overheating and damaging the windings.
  • Overload relays help to prevent accidents by preventing motors from overheating and causing fires.
  • Overload relays can help to prevent motors from failing, which can lead to downtime.
  • Overload relays can help to save money by preventing motors from failing prematurely.
If you are looking for a way to protect your electric motors from overloads, an overload relay is a good option. They are a safe, reliable, and cost-effective way to protect your motors.
