3-phase or 3-phase+neutral line voltage monitoring relay for phase sequence, phase loss, asymmetry, tolerance, over and under voltage (separately adjustable set points) with built-in time delay function. Supply ranges from 208 to 480 VAC covered by two multivoltage relays.
General Characteristics
TRMS 3-phase over and under voltage, phase sequence, phase loss, asymmetry and tolerance monitoring relay
Detect when all 3 phases are present and have the correct sequence
Detect if all the 3-phase-phase or phase-neutral voltages are within the set limits
Detect if asymmetry and tolerance are within the set value
Separately adjustable setpoints
Separately adjustable delay functions (0.1 to 30 s)
Output: 2 x 5 A relay SPDT NE
