Contactors provide switching for starting induction motors.
See Table 1 for contact ratings.
Table 1. Contact Ratings.
CAUTION
Disconnect power supply before beginning
installation to prevent electrical shock or equipment
damage.
Location
Locate the contactor on a flat, solid surface as close as
possible to the equipment being controlled.
Mounting and Wiring
Disconnect power supply before beginning installation to
prevent electrical shock or equipment damage. Be sure all
wiring complies with local codes and ordinances.
IMPORTANT
Do not exceed the contact and coil ratings when
wiring the contactor into the system.
New Installation
쐃 Mount the contactor in a vertical position for best
performance. Horizontally-mounted contactors have
a 12 percent lower efficiency.
쐇 Use two screws to mount the contactor. Select
models use a shear formed panel tab to mount the
contactor. See Fig. 1.
쐋 See equipment manufacturer wiring instructions or
Fig. 2.
쐏 Attach the line wires to the contactor using terminal
clamp screws.
쐄 Attach the load wires using No. 10 binding screws.
쐂 Use pressure lugs for field wiring with wire larger
than No. 8.
