PMR-240

PMR-240 is a 240V phase failure relay designed for reliable protection in industrial power systems. This Boltswitch device monitors three-phase voltage, phase sequence, and phase unbalance, providing adjustable trip delay and under voltage protection for critical applications.Engineered for robust performance, the PMR-240 features front-mounted adjustment pots and LED indicators for voltage, unbalance, and time delay settings. The relay de-energizes its output in response to under voltage, phase reversal, phase unbalance, phase loss, or complete power loss. It is suitable for use in environments requiring dependable phase monitoring and protection.
