Macromatic PLP Series - Phase Loss & Reversal Monitor Relays

Macromatic PLP Series - Phase Loss & Reversal Monitor Relays (Plug-In)
   
The PLP Series Phase Monitor Relays provide protection against phase loss & phase reversal in a compact plug-in design. The relay is energized and the LED on when all three phases are present and in the correct sequence. Any fault will instantaneously de-energize the relay and turn off the LED. Re-energization 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.
 
Features:
  • PLP Series protects against phase loss & phase reversal
  • LED indicates both normal and fault conditions
  • Compact plug-in case utilixing industry standard 8-pin octal socket
  • 10A SPDT output contacts
