GTH-85 thermal overload relay  

Application:

    GTH series thermal relay is suitable for the power system of AC 50Hz, main circuit rated voltage up to 660V, current up to 630A, used as protecting AC three-phase motor against overload and phase losing, and forming electric-magnetic with starter UK series AC contactor.

     It has functions of phase-losing protection temperature campe, trip indication. It can passively and automatically get back.

Characteristics:

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.

4. Easy operation

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.
