TABLE XI
Replacement Circuit Board Catalog Designation
Each catalog designation consists of six or more characters:
Example:
W CB C
1
F Y4
(models A thru F)
W+ CB C
1
F Y4
(models P and later)
Position:
I
II
III IV V VI
Note that Model P and later circuit boards are not mechanically
compatible with earlier models.
Position:
I = Type Designation
W = Advantage Model F or earlier
W+ = Ad Model P or later
K= KW Rated Advantage Model F or earlier
K+= KW Rated Ad Model P or later
Note 1: The Type Designation can be determined by the 1st
character of the Catalog Number listed on the nameplate label
on the front of the device (i.e. W, W+, K, or K+).
Note 2: The Model Designation can be determined by the 1st
character of the Model listed on the nameplate label on the
front of the device (i.e. A, B, C, D, F, P, or R).
II = Category
CB = replacement circuit board
III = Function
C = contactor
O = overload relay
S = starter
IV = Size
3 = size 3
4 = size 4
V = Control voltage and frequency
F = 110-120 volts, 60 Hz
N = 110 volts, 50 Hz
VI = Suffix to indicate modifications that alter the
characteristics above
Y4 = phase loss and imbalance protection
omitted
Y7 = ground current sensing protection omitted
Y10 = phase loss protection omitted
Y11 = phase imbalance protection omitted

Arc box cover must be in place when the contactor
interrupts a circuit.
