thermal overload relay
GTH Series thermal overload relay protect motors from overloading, locking, phase opening (differential) .
1. Direct mounting structure: The thermal overload relay is mounted directly on the magnetic contactors without additional bracket(applied model:GTH-22,40,85) .
2. Safety cover: The finger proof safety cover prevents careless touch of electrical conductor(applied model:GTH-22,40,85)
3. Separation of power part and operation part: The main circuit and the operation part are separately designed and the operation part is commonly used in GTH-22,40,85.
Current Setting: rotating the knob by using +, - shape screw and set the rated current, manual-auto reset setting, manual reset, rotating the reset button to the position of H, and it will protrude, auto reset, rotating the reset button to the position of A, trip/reset indicator, if the thermal overload relay tripped, it will protrude 2-3mm and indicate the tripped condition.
