Product Introduction:
Three-phase thermal relay tester 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.The instrument is small in size and easy to carry. It can detect, set and accept various protective electrical appliances such as circuit breakers, semiconductor circuit breakers, thermal relays, and electronic motor protectors in the laboratory and mobile sites. It is suitable for small workshop sites.

Feature:
1. Three-phase output 0-50A-500A three-phase instrument can be tested at the same time and can be adjusted separately. And can synchronously record the action time with the automatic judgment of the normally closed contact.
2. It adopts multifunctional digital LED display I meter, with intuitive reading and high accuracy.
3. The beautiful and elegant aluminum alloy case with flip cover is adopted, and handles are provided on both sides of the case for on-site moving.
4. The use of imported components makes the load capacity of the instrument extremely strong and adds a more complete electrical protection circuit, which can be connected in series at the same time for verification. Greatly improve the verification efficiency.
5. The output current has been increased to adapt to the setting of commonly used currents and increased to multiple output currents to adapt to the detection of various commonly used electrical appliances. Corresponding improvements have been made to other structures, and the functions are more complete, which provides convenience for use, simplifies the operating procedures, and is more suitable for on-site use.
