Three Phase Vacuum Contactors
RP133
MODEL RP 133-2332-00
Weighing less than 30 pounds, this small contactor
(11.8” x 10.5” x 5.5”) is designed to meet the requirements of today’s modern equipment. The size reduction
is accomplished by utilizing three new Jennings vacuum
interrupters that were developed for this specific purpose.
The vacuum interrupter, a hermetic enclosure in which
the contacts operate, is the key component of this three
phase vacuum contactor. The contact-to-contact gap
required to interrupt the circuit is short, thus permitting
ultra reliable operation. The special contact materials
used are rated for use up to 1.5 kV, 450 amperes load
life and 4500 amperes fault current.
The contactor, which use vacuum as the dielectric and
interrupting medium, is performing better in many
applications than the conventional air magnetic or oil
immersed types that have been in general use. The
contactor is rugged, requires minimal maintenance, is
smaller and lighter than other types, and is environmentally safe and extremely durable. Because of their reliability and durability, vacuum contactors are becoming the
switching device of choice in motor controllers that
operate production and processing equipment, mining
and construction equipment, earth movers or carriers,
power shovels, rock crushers and conveyors.
Designed to withstand the frequent switching required to
control furnaces and large air conditioning motors, the
RP133-2332-00 Contactor is commonly used to protect
power transformers and DC power supplies, and also to
switch capacitor banks for voltage regulation and power
factor correction as a means of reducing operating cost.
Load life of the RP133-2332-00 Contactor is typically
one million operations at rated load current. Maintenance
is minimized as the main contacts are sealed to eliminate
contamination. It operates at an ambient temperature
range of –40° to +85°C.

Three Phase Vacuum Contactors
RP151B
MODEL RP151B
A small, lightweight 3 phase, normally open, 200 amp
vacuum contactor for use in equipment which requires a
high speed interrupt time. It is useful as an overload
interrupter to 2000 amps RMS interrupting capacity.
Special erosion resistant contacts offer long life without
adjustment or contact maintenance at rated current of
200 amps. Typical test results indicate a minimum
electrical load life of 250,000 operations.

MODEL RP 173-2310-00
Weighing less than 67 pounds, this small contactor
(18”X18”x 8”) is designed to meet the requirements of
today’s modern equipment. This small size is accomplished by utilizing three Jennings vacuum interrupters
that were developed for this specific purpose. The
vacuum interrupeter, a hermetic enclosure in which
the contacts operate, is the key component of this
three phase vacuum contactor. The contact-to contact
gap required to interrupt the circuit is short, thus
permitting ultra reliable operation. The special long
life, low chop contact materials used are rated for use
up to 7.2 kV @ 450/600 amperes. See Specifications
for electrical load life.
The contactor, which uses vacuum as the dielectric
and interrupting medium, performs better in applications
than the conventional air magnetic or oil immersed types
that have been in general use. The contactor is
rugged, requires minimal maintenance, is smaller and
