Auxiliary Contacts for C30CN/ECC
A mechanically held contactor
with a two-wire control
module uses 1NC auxiliary
contact as standard for the
control wiring circuit. The
mechanically held contactor
with a three-wire control
module uses 1NO-1NC
auxiliary contacts as standard
for the control wiring circuit.
See the table below for
possible additional auxiliary
contact configurations.

Transient Suppressor Kits for CN35/ECL
10–60A Contactors
These kits limit high voltage
transients produced in the
control circuit when power is
removed from the contactor or
starter coil. There are three
separate suppressors for use
on 24–120V, 240V or 480V
coils respectively.
These devices mount directly
to the coil terminals of
lighting contactors 10–60A.
Kits for 10–60A
100–300A Contactors
This device mounts on top of
any side-mounted auxiliary
contact on lighting contactors
100–300A. It connects across
coil terminals on any 120V
contactor magnet coil.
Limits high voltage transients
produced in the circuit when
power is removed from the
coil.

Auxiliary Contacts for CN35/ECL
CN35 lighting contactors
include a 1NO maintaining
auxiliary contact mounted on
right hand side (on 10A, two-
and three-pole devices,
auxiliary contact occupies
fourth power pole position—
no increase in width). The
10–60A devices will accept
additional auxiliary contacts
on the top and/or sides.
Auxiliary contact blocks are
designed for snap-on
installation—fast, easy
installation (no tools required
up to 60A). All auxiliary
contacts are of the bifurcated
design with parallel circuit
paths. This redundant path
provides very high reliability.
Auxiliary contacts can be
snapped on the side (up to
two circuits—per auxiliary
contact) and on the top (up to
four circuits). Auxiliary
contacts for larger contactors,
100–400A sizes, will accept
side-mounted auxiliaries only
and easily attach to the side
of the contactor with two
screws.
Contact Configuration Code
This two-digit code is found
on the auxiliary contact to
assist in identifying the
specific contact configuration.
The first digit indicates the
quantity of NO contacts and
the second indicates the
quantity of NC contacts.
