Nr8 series thermal overload relay (hereinafter referred to as thermal relay) is used to provide overload and phase failure protection for AC motors with a frequency of AC 50Hz/60Hz, a voltage of up to 690V and a current of 0.1A~38A that operate continuously or intermittently.
The thermal relay also has temperature compensation, operation indication, automatic and manual reset and stop functions and stable and reliable performances.
Standard: IEC 60947-4-1.
Plug-in mounting is used between the thernal relay
and the contactor.
