CII 1400 series phase sensors
combine solid state sensing
circuits with electromechanical
output relays in robust
hermetically sealed enclosures.
P-Type models are for static
loads. With the line voltage and
frequency are within operating
limits, P-Type units will energize
only when input phases are in
sequence A-B-C. They will de-
energize only when power is
removed. The P-Type unit is
best suited to applications
where static loads are used
and where regenerated voltage
will not be present if a phase
opens.
Q-Type units perform the
same function as the P-Type
since they will energize only
when input phases are in
sequence A-B-C. In addition,
the Q-Type unit will de-energize
when any phase is discon-
nected or grounded, provided

the voltage input to the unit is
below 50% of the nominal
phase-to-phase voltage input.
Q-Type units are suitable for
motor loads where regenerated
voltage is produced.
Neither P-Type nor Q-Type
units require connection to the
neutral leg.
For high-current applications,
phase sensors are used with
slave relays having heavy duty
contact ratings.
