Monitoring Relays
3-Phase Sequence and Phase Loss
Type
EQB62DN55
Product Description
3-Phase relay for detection of incorrect phase sequence,
total or partial phase loss. Supply range from 208 to 480 VAC.
For mounting on DIN- rail. Housing 17.5mm wide,SPDT relay
output,suitable for back and front panel mounting.
The device detects regenerated voltage up to 85% of the
nominal voltage (phase to phase).
Property
• 3-phase monitoring relay for phase
sequence and phase loss
• Detects when all phases are present and have the
correct sequence
• Measures its own power supply
• Power supply range: 208 to 480 VAC (±15%)
• Output: 5 A SPDT relay normally energized
• For mounting on DIN-rail in accordance with
DIN/EN 50 022
• 17.5 mm DIN-rail housing (DIN 43880)
• LED indication for relay and power supply ON
