Multipole lighting contactors

General
Lighting contactors have evolved from the need for more
than just simple on-off manual control of lights. Today's
requirements call for the development of new and varied
types of control. Often the application will call for remote
control of lighting from some distant location. This control
may not be in addition to a master control station at a
central location. Certain applications include the use of
automatic control by time clocks or photoelectric cells.
Whatever the need may be, applications are increasing and
lighting contactors are designed to meet the ever-changing
requirements.
Typical installations include:
b Parking lots.
b Industrial plants.
b Office buildings.
b Theatres and auditoriums.
b Hospitals and institutions.
b Shopping centres.
b Stadiums.
b Airports.
