How to view device information of MICOM relay protection device

Under the openable upper cover plate, the identification paper of the device is affixed, on which there are information such as the model, serial number, sensitive grounding current range, rated value and order code of the protective device. 

The meaning of each information is listed below: P127CAF11: CORTEC code (order code) Through this code, users can know the characteristics of the protective device. No.: 

0000000: the serial number of the device; Cde: 00000/000: Device ordering reference information. When there is a problem with the device, the user must provide this information for repair. 

Un = 57 130V: Range of voltage transformer input. 

Modbus: Communication protocol, realized through the rear RS485 communication port. 

0.002 len: Sensitive ground fault current level (there are three sensitivity levels). 

Ua = 48-150Vdc: The voltage range of the unit's power supply. In this example, the power supply can only be DC DC.
