Size 1 Contactor
Product Description —
Sizes 00 – 4
Application
Magnetic contactors are used to
switch transformers and capacitors
and to control electrical power circuits
such as heating, lighting and motors
that require no overload protection, or
where overload protection is sepa-
rately provided. They can be operated
remotely by manual or automatic pilot
devices.
Class A201 Contactors, Sizes 00 – 4;
Three-Phase, 1-1/2 – 100 hp
A201 Magnetic Contactors from
Eaton’s electrical business are 600V
rated devices available in NEMA Sizes
00 – 4, 10A through 150A (open rating).
Product features include:
■ Straight-through wiring to line and
load terminals located up front for
ease of installation.
■ Moving and stationary contacts are
front accessible, simplifying inspec-
tion and maintenance.
■ Reliable U-shaped magnet for
reduced power consumption.
■ Coil design reduces inventory/main-
tenance expenses. For a given volt-
age, one size coil fits all contactors
Sizes 00 – 2, and a second coil fits
three-pole Model J Sizes 3 and 4.
Model K coils are different design.
A201 contactors have normally open
holding circuit interlocks which are
supplied as standard.
Panel layout and drilling are simplified
through the use of common backplates,
one for Sizes 00 – 2 and one for Sizes
3 – 4. In addition, panel space is
reduced dramatically through the use
of unique corner cavities for mounting
the wide variety of modifications
shown on Page 33-166.
For reversing applications, two contac-
tors are supplied on a common base
with electrical and mechanical inter-
locks which prevent both contactors
from being closed at the same time.
A201 contactors are UL listed compo-
nents and also have CSA certification.
