Auxiliary Contact Units
Additional auxiliary contact units may be added to
the Size 4 and 5 reversing contactors in the field.
A maximum of 2 units may be added to the Size 4;
a maximum of 1 unit may be added to the Size 5.
No additional units may be added to the Size 6,
however, 1 N.O. and 1 N.C. circuit are available on
each forward and reverse contactor for customer
use.
GENERAL INFORMATION
Class 8702 Type W reversing vacuum contactors
are a new addition to the Square D line of
contactors. These reversing contactors are used
to switch capacitors, transformers and electric
motors where overload protection is separately
provided. Type W reversing vacuum contactors
are designed for operation at 600 Volts, 50/60
Hertz.
By design, these contactors are well suited to
heavy-duty applications in harsh environments.
The power contacts are sealed in ceramic tubes,
called vacuum interrupters or vacuum bottles,
where the air has been evacuated. Arc quenchers
are not required because any arc formed between
opening contacts is not sustained due to the
presence of the vacuum. The arc is extinguished
when the current crosses zero after the contacts
are opened, therefore the arc typically does not

survive more than one half cycle. There is one
vacuum interrupter or bottle per pole, therefore a
three pole contactor has three vacuum
interrupters or bottles. The power contacts are not
affected by ambient conditions or contamination.
This provides for long life and reliable operation in
harsh applications.
Altitude
The reversing vacuum contactor is designed to
tolerate normal barometric pressure variances up
to 6600 feet above sea level. If the contactor is to
be used above 6600 feet above sea level, please
consult the factory.
Termination Means
The Size 4 reversing vacuum contactor is
supplied with line and load side lugs. The Size 5
and 6 reversing vacuum contactors are supplied
without line and load side lugs. Class 9999 Type
LUW5 and LUW6 lug kits are available for the Size
5 and 6 contactors. These kits include six lugs and
the necessary mounting hardware.
Auxiliary Contacts
An auxiliary contact block, Class 9999 Type
WX11, with one normally-open contact and
normally-closed contact is used with Size 4, 5 and
6 vacuum contactors.
