2 POWER POLES: CR460XP31 / 32

2.1 Description

Power poles are available in both single pole (CR460XP31)
and double pole (CR460XP32) 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 pole,

refer to the Table A below.

3. Remove block by pulling the clip as shown (see Figure 2).

Rotate block 180 degrees to convert from NO to NC.

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 Table D on page 3 for the wire size and the

kit includes an additional single-pole auxiliary contact block.
Refer to the Ordering Detail section for more information on
the control module kits and the control voltages available.

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). Refer to Table

3 AUXILIARY CONTACTS: CR460XB1/XB2

3.1 Description

The auxiliary contact blocks are available in both single pole
(CR460XB1) and double pole (CR460XB2) 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 Table D on page 3 for
wire size and required torque.

4 CONTROL MODULE KITS

The base (electrically held) can be converted to a mechanically
held type by adding the 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 the “control module kit” to the base.

4.1 Description

Control modules kits are available both for 2-wire and 3-wire
control with a wide range of control voltage inputs. 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 and the latch cover as shown in Figure 5.

Operation tab

3. Be sure the latch is firmly in place with the wire facing out

and the slot positioned with tab inserted.

4. Operate contactor manually, using manual operation tabs

on side, prior to installing cover to insure correct
installation.

Note: Once latch cover has been installed, it may not be
removed.

5. For 2-wire control, the auxiliary contact block is

assembled to the right side of the base for “NC”.

IMPORTANT: Latch and electronic module must be used
together to ensure proper operation. Failure to do so will void
warranty.

4.3 Wiring

Follow the schematic (Figure 6) for 2 and 3-wire control.
Refer to Table D on page 3 for wire size and required torque.

Note: For 2-wire control, ensure the two wires coming from
the control module are connected across a NC auxiliary
contact.
