Instructions for Class W200, W201, Sizes 3 and 4, Three Phase
Non-Reversing Magnetic Motor Starters and Contactors

ADVANTAGE MOTOR CONTROL
Advantage NEMA Size 3 and 4 electrically-operated star-
ters and contactors (motor controllers) have the same
physical size, but differ with respect to mechanical parts
and settings available.
The motor starters (Class W200) include a solid state
current-sensing unit that provides overload protection,
phase loss protection, phase imbalance protection, and
ground current-sensing protection.
The motor rated contactors (Class W201) do not include
overload, phase loss, phase imbalance, or ground current-
sensing protection, but they do have the same coil con-
troller that prevents a contact kiss position on pickup
and dropout when the coil voltage supply drops drastically.
Both starters and contactors have this low voltage release.
Both require a separate source of control power, preferably
taken from the motor supply circuit via a control power
transformer.

RATINGS
The maximum horsepower ratings of these motor con-
trollers are shown in Table I.
Kilowatt ratings equivalent to the horsepower ratings
shown in Table I are shown in Table II.

PROGRAMMED FEATURES
Advantage NEMA Size 3 starters and contactors are
assembled with identical parts except for the circuit board
to which the control wires are attached. These circuit
boards differ with respect to components and the software
program they contain.
NEMA Size 4 starters and contactors are likewise similar.
They differ from Size 3 devices by virtue of larger contacts,
higher ratings and different programs.
Phase Loss Protection -
Advantage starters with this
option automatically open (trip) within 2 seconds after
they sense a current less than 7 amperes through any
phase after power is applied to the motor. This protection
prevents damage when a lead in a motor branch circuit
has been lost.
Phase Imbalance Protection -
Advantage starters with
this option automatically open (trip) within 9 seconds after
they sense an imbalance between two phase currents
that is greater than 30% of the Trip Rating shown in Tables
IV and V. This protection prevents motor damage when
a lead in a distribution system has been lost.
