Description
The Cutler Hammer C30CN Series is a magnetically operated
lighting contactor, and is available in both open and enclosed
forms. These contactors are field configurable for up to twelve
poles, with a maximum of eight normally closed “NC” poles.
Figure 1: Mechanically Held Contactor
1 MAIN BASE
1.1 Description
The base of the lighting contactor (see Figure 1) has provisions
to accept power poles at positions “1” to “6”. Provisions are
also provided for up to 2 “NO” and 2 “NC” auxiliary contacts.
1.2 Installation
1. Remove all packing material from the base and all the kits.
2. Contactor must be mounted in the vertical position on a
sturdy support.
3. Additional over-current protection may be required. Refer
to the National Electrical Code or local electrical code as
required.
4. Refer to Section 5.3 and Table D on page 3 for the wire
size and the required torque for the coil terminals.
2 POWER POLES: C320PRP1 & C320PRP2
2.1 Description
Power poles are available in both single pole (C320PRP1) and
double pole (C320PRP2) versions. A maximum of twelve
poles may be installed on the base. Positions “1” to “4” on the
base can be configured as either normally open “NO” or “NC”
while positions “5” and “6” can be configured as “NO” only.
2.2 Removal and Conversion of Power Poles
1. If installed ensure that all power is disconnected.
2. For multiple possible configurations of the power poles,
refer to Table A below.
Table A
3. Remove block by using a screwdriver to pull the clip as
shown (see Figure 2). Rotate block 180 degrees to convert
from NO to NC or from NC to NO and install per 2.3
below.
Figure 2
2.3 Installation of Power Poles
1. Check moving carrier to assure free movement
2. Install the block by sliding foot into slot; using a
screwdriver pull the clip, and position block onto base.
Release the clip.
3. Check for the lettering on the base. “NO” should be
visible if the power pole is assembled as normally open,
and “NC” should be visible if it is assembled as normally
closed (see Figure 3).

2.4 Wiring
Power poles can accept wires from #14 to #8 AWG (either
solid or stranded) as single or combination of two wires (refer
to Table B below for valid wire combination). Wire material
must be copper with a temperature rating of 75 degrees C.
Maximum tightening torque is 35 in-lbs.

3 AUXILIARY CONTACTS: C320AMH1 & C320AMH2
3.1 Description
The auxiliary contact blocks are available in both single pole
(C320AMH1) and double pole (C320AMH2) versions.
Auxiliary contacts can be added on either side of the base (see
Figure 1). When added to the LEFT side of base, the auxiliary
block functions as “NO”, and when added to the RIGHT side
of base it functions as “NC”. Refer to section 4.3 for wiring.
4 CONTROL MODULE KITS
The base (electrically held) can be converted to a mechanically
held type by adding a control module kit.
IMPORTANT: The control module kits are for use with the
coils up to 277 VAC maximum. Use a control power
transformer for higher voltages.
Conversion from an electrically held to a mechanically held
type is possible by adding a “control module kit” to the base.
4.1 Description
Control module kits are available both for 2-wire and 3-wire
control with a wide range of control voltage inputs. Figure 4
shows the components in 2-wire control module kit. A 3-wire
kit includes an additional single-pole auxiliary contact block.
Refer to the Ordering Detail section for more information on
control module kits and control voltages available.
Figure 4
4.2 Installation
1. Disconnect all power and mount the control module on the
contactor as shown in Figure 1 (3-wire control type).
2. Mount the latch as shown in Figure 5.
Figure 5 – Caution: Once latch cover has been installed,
it may not be removed. Ensure latch is properly installed
prior to installing the latch cover.
3. Be sure the latch is firmly in place with the wire facing out
and the slot positioned with tab inserted.
4. Mount the latch cover as shown in Figure 5.
Caution: Once latch cover has been installed, it may not
be removed. Ensure latch is properly installed prior to
installing the latch cover.
5. For 2-wire control, the auxiliary contact block is
assembled to the right side of the base for “NC”.
6. Operate contactor manually, using manual operation tabs
(See Figure 5) on side, prior to installing cover to insure
correct installation.
IMPORTANT:Latch and electronic module must be used
together to ensure proper operation. Failure to do so will void
warranty.
4.3 Wiring
Control module’s and auxiliary contact block’s terminals can
accept a single wire from #22 to #12 AWG (either solid or
stranded). Maximum tightening torque required for the
control module’s terminals is 5 in-lbs. Auxiliary contact
block terminals can accept parallel conductor size
combinations utilizing torques identified in Table C.

Follow the schematic (Figure 6) to wire the 2 and 3-wire
control modules.
Note: For 2-wire control, ensure the two wires coming from
the control module are connected across a NC auxiliary
contact.

5 COIL KITS
5.1 Description
A wide range of coils is available for both electrically held and
mechanically held lighting contactors. Refer to the Ordering
Detail section for more information about the coil kit catalog
numbers and voltages available.
Note: For mechanically held lighting contactor, only use coil
rated up to 277 VAC maximum. Use control power
transformer for higher voltages.
5.2 Installation
1. Disconnect all power. Replace and mount the coil on the
contactor as shown in Figure 7.
2. For mechanically held contactors, remove all wires from
the control module and remove the coil cover along with
control module.
5.3 Wiring
Coil terminal can accept wires from #18 AWG to #14 AWG
(either solid or stranded) as single or combination of two wires
(Refer to Table D below for valid wire combination). Wire
material must be copper with a temperature rating of 60 or 75
degrees C. Maximum tightening torque is 15 in-lbs.
