描述 Description

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.

Operation

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

the fault.
