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. |
