This three-phase monitor relay detects phase loss, low voltage, and phase reversal, ensuring motor safety and reliable operation. It features a solid-state sensing circuit driving an electro-mechanical relay, which energizes under correct voltage and phase rotation. When faults occur, the relay de-energizes, providing a clear electrical signal. The device offers both automatic and manual reset options, does not require neutral connection, and is compatible with Wye or Delta systems. It is protected against transient voltage spikes up to 2500 V for 10 ms, and includes indicators for trip and normal conditions, making it vital for industrial power systems.
