C30 Lighting Contactors
Application Description
Operation
The mechanically held lighting
contactor provides effective control
in applications such as office buildings, industrial plants, hospitals,
stadiums, airports, etc.
■ They are ideal for applications that
require quiet operation.
■ Mechanically held operation
assures that the contactor will not
switch to OFF during control circuit
power failure.
The standard contactor, which is controlled by a separate customer supplied
single-pole, double-throw control
station, is both electrically operated
and mechanically held with no continuous control current required. It is
inherently interlocked and mechanically held in both the open and closed
positions.

C30 Lighting Contactors
Product Description
■
■
The C30 Mechanically Held Lighting
Contactors are designed to handle the
switching of tungsten (incandescent
filament) or ballast (fluorescent and
mercury arc) lamp loads as well as
other non-motor (resistive) loads. The
mechanically held operation ensures
that the contactor will not switch to
OFF during control power failures.
■
■
Designed and tested specifically for
lighting and resistive loads
Holds up to 12 poles in compact
frame
Quiet performance while contacts
are mechanically held together
Contacts will remain closed during
loss of control power and allow load
to operate as soon as power is
restored
Each power contact has a separate
indicator which designates contact
position
A momentary pulse drives the contacts
to both the open and closed positions,
thus eliminating the need for dualsolenoid operators, magnetic latches,
gravity drop out and field adjustments.
Coil clearing contacts are completely
enclosed and assure that the coil will
be de-energized, even if the remote
control station is held closed.
