Phase sequence Three Phase Voltage Monitoring Relay Miniature voltage relay


Phase sequence protector is a type of control relay that can automatically identify the phase relay protection relay, to avoid some special mechanical and electrical equipment because of reverse phase after power reversed and cause accident or equipment damage.


Phase sequence protector is a kind of control relay, automatic phase sequence identification protection relay, guarantee some special electromechanical equipment

The reversed phase sequence of the power supply reversed the accident or equipment damage. Such as elevators, central air conditioning, cranes, motors, etc. If the phase sequence of the power supply is wrong after repair, it will lead to accidents. The phase sequence protector must be connected to the control circuit to ensure the phase sequence is correct. Air-conditioner compressors also use phase sequence protectors to ensure that the compressor will not be reversed after maintenance.
