Macromatic PCP Series - Phase Reversal Monitor Relays

Macromatic PCP Series - Phase Reversal Monitor Relays (Plug-In)
The PCP Series Phase Monitor Relays provide protection against phase reversal in a compact plug-in design. One version will work on any 3 phase system from 208V to 480V (a separate 120V-only version is also available). The relay is energized and the LED on when the sequence is correct. Any fault will de-energize the relay and turn off the LED. Reenergization is automatic upon correction of the fault condition.

These devices are designed to be compatible with most Wye or Delta systems with no connection to Neutral required.
  • PCP Series protects against phase reversal only
  • LED indicates both normal and fault conditions
  • Compact plug-in case utilixing industry standard 8-pin octal socket
  • 10A SPDT output contacts
