This three-phase monitor relay continuously checks power systems for phase loss, phase reversal, and low voltage conditions. Designed for 208/240 VAC at 400 Hz, it features a solid-state sensing circuit that energizes an electro-mechanical relay under normal conditions. When faults occur, the relay de-energizes, signaling abnormal system conditions. Suitable for Wye or Delta systems, it offers adjustable settings, front indicators, and a robust build with UL recognition. The relay's high reliability is supported by a 5-year unconditional warranty, making it essential for industrial motor protection and power quality monitoring.
Experience unmatched reliability with the Time Mark 258BM400 three-phase power monitor relay. Designed for precise fault detection, it offers automatic and manual reset options, several voltage ranges, and high endurance rated for industrial applications. Easy to install with a plug-in 8-pin socket, this device provides accurate system monitoring for phase loss, reversal, and low voltage conditions.
