|
Application
|
GTR2 Series overload relays apply to circuit of AC 50Hz or 60Hz,rated voltage to below 660V and rated current 0.1A~93A for AC motor overload and open-phase protection during long time or intermittent long time service,which can also protect 3-phase serious imbalance and long starting time of motor or long time operation, can also be used for corresponding AC contactor for electromagnetic starter.
This product has innovative, elegant model and small installation area, functions such as temperature compensation,action indication,automatic and manual reset, stop with steady and reliable performance
Thermal relay can be combined/connected with contactor or installedseparately.
Standard: IEC 60947-4-1
