Phase Sequence Protection Relay for Motor Safety

Three-phase phase failure phase sequence protection relay   This three-phase phase failure and phase sequence protection relay is a safety protection electronic control component specifically designed for industrial three-phase motors. It uses the detection principle of resistance capacitance phase-shifting combined with voltage comparison to accurately determine the operating status of the three-phase circuit, and specifically solves common circuit faults such as motor phase loss and phase sequence reversal. The product has a simple and reliable working logic, and the internal contacts remain closed when the circuit is normal, allowing the motor to start and operate normally; Once abnormal conditions such as phase failure, phase mismatch, and voltage imbalance are detected, the contacts will quickly disconnect the control circuit, forcing the motor to fail to start or stop urgently, avoiding motor burnout, equipment jamming, circuit short circuits, and other faults.
