Product Description
The Cutler-Hammer
Mechanically Held Lighting Contac-
tors from Eaton’s electrical business
are designed for industrial, commer-
cial and outdoor lighting applications
where efficient control is required. The
mechanically held operation ensures
that the contactor will not switch to
OFF during control power failure. It
also ensures the removal of coil from
the circuit for noise-free operation and
the elimination of all coil losses after
the contactor is latched. The control
module microprocessor validates the
control signal before operation, so it
will not respond to momentary voltage
spikes of noise. The operation com-
mand has a built-in .4 sec delay to
avoid multiple short-term commands
that can cause contact fatigue or fail-
ure. Also, the feedback loop prevents
the contactor from getting out of
sequence with switches, even after
power failures.

30 amp power pole rating
Up to 12 poles maximum
Power poles latch easily onto the
base, and designating them as NO
or NC is a simple matter of left or
right positioning. Additional poles,
either NO or NC, may be easily
added at any time.
Low magnetic noise results in quiet
operation
Low input VA permits long wire runs
Come in a wide range of input volt-
ages and with coils from 24V to
277V AC and 12V to 24V DC.
Common easily-installed power poles
change from NO to NC (or vise versa)
simply by unlatching and rotating 180°
Plug-in auxiliary contacts are NC
when installed on the right side
of the base, NO on the left
Power poles rated for a range of
tasks:
