Thermal Overload Relay/Thermal Relay/GTH thermal relay

Thermal Overload Relay/Thermal Relay/GTH thermal relay
Product Detailed
GTH22,GTH40,GTH85 thermal overload relay

GTH series thermal overload 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 these relays 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.
