Industrial Control — Thermal Overload Relay

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.
