Monitoring Relays
3-Phase Sequence and Phase Loss
Type DPA53
Product Description
3-Phase monitoring relay for detection of incorrect phase
sequence and phase loss. Using the front knob it can be decided
the undervoltage setpoint of the unit.
Supply range from 208 to 240VAC or 380 to 480VAC covered by
two multivoltage relays. For mounting on DIN-rail.
Housing 17.5mm wide suitable both for back and front panel
mounting.
