HGT | Adjustable Current Thermal Relay | HGT18–HGT800

Thanks to the protective cover, the front face of the adjustment mechanism is securely protected by a transparent cover, preventing external interference with the set current value or the reset operation. When the test button is used for emergency stopping while the motor is running, it opens the contactor contact and stops the motor; additionally, pulling the test button to verify the correct operation of the thermal relay contact changes the contact position and performs the test. The current adjustment screw allows precise adjustment of the rated current value in ± three steps using a screwdriver.
