When Ordering Specify —
■ All Non-reversing and Reversing
motor controllers are selected based
on the overload current range
required for a given motor. This
current range is determined from
the motor Full Load Ampere rating
and Motor Service Factor usually
found on the motor nameplate.
■ For motors with service factors less
than 1.15, multiply the motor FLA by
.92 to select the appropriate motor
controller. Example: For a motor
having FLA of 12.5A and a service
factor of 1.0 (12.5A x .92 = 11.5A)
select Catalog Number
N307WNS0X3N.
■ For motors with service factor of
1.15 or greater, use motor name-
plate Full Load Amperes to select
the appropriate motor controller.
Example: For a motor having FLA
of 12.5A and a service factor of 1.15,
select Catalog Number
N307XNS0X3N.

C320WC45IT and N111BS0X3N.
■ The Reversing Catalog Number is a composite of the factory assembled Line Side Adapter, Manual Motor Protector,
Mounting Plate and the IT. Contactor. E.g. Catalog No. N357VNS0X3N is the combination of C320LSA1, A307VN and
N511BS0X3N.
