Output Specifications
DPA 01 C M44
3-phase relay for detection of
incorrect phase sequence,
total and partial phase loss.
Supply range from 208 to 480
VAC covered by one multi-
voltage relay (or by two multi-
voltage relays for DPA01D
models). For mounting on
DIN-rail or plug-in module.
The device detects regener-
ated voltages up to 70% of
the mains nominal voltage
(phase-neutral).
