622-8822: Thermal Overload Relay

The Thermal Overload Relay is a safety device used in conjunction with motor starters. Its function is to safeguard electric motors from damage caused by excessive heat. It consists of two bonded metal layers with differing rates of thermal expansion. When current flows through a heating element within the relay, the bimetallic strip heats up. It has a heating element, and a resistive coil, that converts electrical current into heat. The relay has a set of electrical contacts that open the circuit when the bimetallic strip reaches a specific temperature. A reset button allows manual restarting of the relay after the motor cools down.

Attributes:
• Provided with screw-type terminals for a secure and reliable connecting method
• Rated with IP20 Protection which signifies the level of protection against dust and solid elements

Applications:
The Thermal Overload Relay is used to protect the motor from overheating. It detects the motor's current and temperature and initiates a response if the values exceed the predetermined limits.

• Material: Plastic Plastic
