Protects against phase loss & reversal; over, under & unbalanced voltages; short cycling
Fixed trip points & delays
Adjustable voltages from 208 to 480VAC in 4 ranges
Monitor 600VAC lines by connecting VRM accessory
Isolated, 10A, SPDT output contacts
Bi‑color LED indicates: output status, faults, time delays, phase reversal & setpoint
Provides protection for motors and other sensitive loads. Continuously measures the voltage of each of the three phases using a microcomputer circuit design that senses under and overvoltage, voltage unbalance, phase loss, and phase reversal. Protection is provided even when regenerated voltages are present. Includes a trip delay to prevent nuisance tripping and a restart delay to prevent short cycling after a momentary power outage
