Thermal Overload Relay is designed to protect asynchronous electric motors from overload and overheating. The relay operates when the set current is exceeded, ensuring automatic disconnection of the protected equipment.

Main Parameters:

• Current adjustment range: 80.00-100.00 A
• Size: S3
• Operating principle: bimetallic element with thermal expansion
• Function: motor overload and overheat protection
• Reliability: automatic reset after tripping upon cooling

The relay is installed in the motor control or protection circuit, providing reliable protection against prolonged overload and preventing winding damage.
