Time Mark B264

PHASE MONITORING RELAY, 208-240 VAC, 1 SPST-NO, 1 SPST-NC, SCREW, 264 SERIES

The Model 264 3-Phase Monitor continuously monitors 3-phase Wye or Delta systems for abnormal conditions. The solid-state electronic sensing circuit drives two separate single pole relays, one normally open and the other normally closed. An adjustable trip delay reduces or eliminates nuisance tripping caused by momentary voltage fluctuations on motor start-up. Standard versions are 120V, 208/240V, 480V and 575V at 60Hz, and 380V at 50Hz. Voltage ranges are sufficiently wide to allow for proper adjustment to existing conditions. Both TRIP and NORMAL indicators are provided to aid in trip point adjustments and system troubleshooting. The Model 264 is not sensitive to line current and can be used with any size motor or compressor.
