TKRJ- electronic thermal relay calibration is mainly used for setting and calibration of various thermal relays and motor protection devices. Because of its reasonable design convenient operation and high output power it is widely used in electric test sites of power system railway petrochemical metallurgical and mining enterprises.

1. It can output three-phase 0-500a current at the same time.

2. It can synchronously test the action time of thermal relay thermocouple and motor protector.

3. Normally open and normally closed contact detection.

4. Several calibrations can be connected in series at the same time to improve working efficiency.
