REVERSE PHASE RELAY
10A 120VAC PLS Series
The PLS Series is a low cost phase sensitive control that
provides an isolated contact closure when the proper A-B-C
phase sequence is applied. Protects sensitive 3-phase
equipment and equipment operators from reverse rotation.
Designed to be compatible with motor overloads or other
3-phase equipment protection devices. Protection for equipment
control centers where frequent reconnection or electrical code
makes reverse rotation protection essential. Examples include:
mobile refrigerated containers, construction equipment, hoists,
pumps, conveyors, elevators and escalators.
The internal relay and LED are energized when the phase
sequence is correct. The output relay will not energize if the
phases are reversed. Reset is automatic upon correction of
