Applications
Class 40 industrial magnetic contactors
are designed for electrical loads such as
heating, lighting, transformer and capaci-
tor switching, and AC motor starting.
They control motors already protected by
inherent or other types of overload
devices. Used with appropriate pilot con-
trol, a contactor provides a choice of
undervoltage protection or release.
Class 40 contactors Size 0 thru 6 feature
carefully wound coils encapsulated to
seal out moisture. Encapsulation also pro-
motes heat transfer and resists electrical,
mechanical, and thermal stresses.
Features
Horsepower rated contactors are avail-
able in NEMA sizes 00 through 6, plus
four Siemens Furnas Half Sizes: 1

. These contactors are avail-
able as an open type or in NEMA 1, 3, 4,
4X, 7 & 9, or 12 enclosures. These con-
tactors can also be used on capacitor and
transformer switching applications.
Resistance heating contactors are avail-
able in 11 sizes from 10 through 350
amperes in 2- and 3-pole models and in 4
sizes in 4-pole models.
Lighting contactors are available in 11
sizes from 20 through 600 amperes in 2-
and 3-pole models and in 3 sizes in 4-
pole models. Lighting contactors are
especially designed to switch ballast
type, tungsten, and other discharge type
lighting loads. These contactors may be
controlled by timers and other pilot
devices.
These contactors are also available with a
DC coil and rectifier for reduction of AC
hum in noise-sensitive areas such as hos-
pitals, schools, and similar locations.
For information and availability of
mechanically held lighting contactors,
contact your local sales office.
