Thermal Overload Relay
SRP series

The protection of overheat is sensitive, safe and reliable to ensure the
stable operation of the motor.

  • Product Description

                           

    The SRP Thermal Overload Relay is a protection device specially designed for motors. It reliably protects the motor from overload damage through precise current settings and fast response capabilities. Its bimetallic strip working principle ensures that the circuit is quickly cut off under overload conditions, ensuring the safe and stable operation of the electrical system.

    The SRP thermal relay is equipped with an adjustment knob, allowing flexible setting of protection values based on motor rated current and overload characteristics, with easy operation without tools. Its compact design simplifies installation and maintenance, making it a reliable electrical safety component in industrial environments.
