GTH series overload thermal relay are suitable for overload and phase-failure protection of AC motors with frequency of 50/60Hz, voltage up to 690v, current up to 0.1-85A under 8-hours duty or uninterrupted duty.
Several functions provided by thermal relay are:
Phase-failure protection, temperature compensation, ON/OFF indication, Stop button, Test button and manual/automatic reset.
Applicable Standards
National Standard: GB 14048
International Standard: IEC 60947-4-1
These thermal overload relays can be mounted onto contactors or installed as single units.
Characteristics
*Direct mounting structure
The GTH is mounting directly to the Magnetic Contactors without addition brackets.(Applied model:model:GTH-22,40,85)
*Safety cover
The finger proof safety cover prevent careless touch of electric conductor(Applied model:GTH-22,40,85)
*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
*Easy operation
