Monitoring Relays
3-Phase unbalance
DPA51CM44 B009
Product Description
3-Phase relay for detection of phase -phase unbalance voltage.
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 phase to phase unbalance voltage.
Using the front knob it can be decided unbalance limits of
the unit.
