WHERE
TO USE GE CONTACTORS
Normally
Open
IC2800B310
contactors are used where time-delay opening of
power circuits such as dc motor loads and resistor
loads are required. They are normally open, single-pole
contactors constructed with copper-jacketed coils
which provide time delay on dropout. The contactors
are front-connected and can be mounted on either
insulating or noninsulating panels.
Normally
Closed
Used
to short-out resistance steps in starting dc motors.
Contactors are normally closed, without blowouts,
and are not designed to interrupt power.
Pick-up
is instantaneous. Time-delay dropout results from
use of a copper-jacketed coil and adjustment of
this time delay is obtained by using a non-magnetic
armature shim. Time delay of IC2800A501 contactors
can be adjusted over a narrow range by the armature
spring. Time delay of IC2800Y109 contactor can
be adjusted over a wide range by a sliding shim.
Mount
contactors on either metal or insulating panels.
Make connections from the front.
