Contactors--Non-Reversing and Reversing
most commonly used to switch motor loads in applications where
running overcurrent protection is either not required or is provided
separately. Contactors consist of a magnetically actuated switch
which can be remotely operated by a pushbutton startion or pilot
device such as a proximity switch, limit switch, float switch,
auxiliary contacts, etc.
contactors are used primarily for reversing single- or three-phase
motors in applications where running overcurrent protection is
either not required or is provided separately. They consist of two
contactors mechanically and electrically interlocked to prevent lint
shorts and energization of both contactors simultaneously.
Benefits and Functions
- Designed specifically for use in
applications requiring NEMA ratings. Contactors meet or exceed
NEMA standards ICS 2-1993
- Long life twin break, silver cadmium
oxide contacts-provide excellent conductivity and superior
resistance to welding and arc erosion
- Designed to 3,000,000 electrical
operations at maximum hp ratings up through 25 hp at 600V
- Steel mounting plate standard on all
open type contactors

occupies 4th power pole position--no increase in width)
Sizes 4-5 have a NO contact block
mounted on left side

Class A201 Contactors, Sizes 00-4; Three-Phase,
A201 Magnetic Contactors from Eaton's electrical sector 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
stationary contacts are front accessible, simplifying inspection
U-shaped magnet for reduced power consumption
reduces inventory/maintenance expenses. For a given voltage, 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
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
For reversing applications, two contactors are supplied on a common
base with electrical and mechanical interlocks which prevent both
contactors from being closed at the same time.
Class A201 Contactors, Sizes 5-9; Three-Phase, Over 100
These AC magnetic contactors utilize clapper design and feature
Contacts are silver alloy for longer life. the contacts close with
optimum wiping action which serves to keep the contacting surfaces
clean. De-ion® arc quenchers draw the arc away from the contacts
at opening, which reduces burning and pitting and increases contact
All of the contactors are complete with one unwired, normally-open
(NO) auxiliary contact mounted and have accommodations for
additional auxiliary contacts. No control circuit wiring or terminal
markings are included.
Size 5, 300A, 600V, Open
Size 6, 600A, 600V, Open
Class A201 Size 5 and 6 contactors are front clapper design, AC
operated with the armature pivoting on dual needle bearings which
assure accurate contact alignment.
The contactor base is molded of a high impact, non-tracking,
non-hygroscopic glass polyester material permitting front mounting
and wiring on a steel panel.
Floating magnet assures quite operation.
Size 5 and 6 contactors must be mounted with the line terminals
directly above the load terminals.
Multi-voltage coil ratings allow selection of the voltage which
closely matches the actual system voltage to assure optimum
Each contactor accommodates two Type J11 auxiliary contacts,
providing up to to four auxiliary circuits, normally-open or
normally-closed (NO and NC).
A201 Size 5 and 6 contactors and starters are UL recognized when
supplied without terminals. When supplied with terminals, the
devices are UL listed.
Two special configurations of the Class A201 Size 5 and 6 contactors
This is a mechanically held, electrically released device. It is
applied where the contactor must remain closed during extreme
voltage fluctuations or power failure. It is also suitable for
applications requiring quiet operation since the operating coil is
de-energized when the contactor is closed. The latch assembly
consists of a mechanical latch mechanism, electrically operated AC
trip solenoid and a clearing contact
This device is DC operated. It is used where low dropout voltage or
exceptionally quiet operation is desired. The DC assembly consists
of a DC operating coil, integrally mounted rectifier and shorting
