CER3 Thermal Relay-Relay-CEA Group International Co., Ltd

◆Application

CER3 thermal relay is suitable for using in power system with AC 50Hz,rated operation voltages up to 660V and 1000V,in main circuit,current from 0.1Ato 630A.It is used to protect AC three-phase asynchronous motor against overload and open-phase.

The current setting value can be regulated and the setting current value of many thermal elements are intercrossing arrangement,for easy selecting by the customers from-25 ℃ to +55 ℃ air temperature as the products have temperature compensating.The relays have the test pushbutton for breaking NC contacts,the operating indication and free trip characteristics,It conforms to 1EC60292-1,IEC60337-1&VDE0660.
