MAXGE SGR2-D Series Thermal Relay
The working principle of the thermal relay is that the current flowing into the heating element generates heat, which causes the bimetallic strips with different expansion coefficients to deform. When the deformation reaches a certain distance, it pushes the connecting rod to break the control circuit, thereby making the contactor When the power is lost, the main circuit is disconnected to realize the overload protection of the motor.
