Eaton A200 Series Contactors

Class A201 Contactors, Sizes 00–4; Three-Phase, 1-1/2–100 hp

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
• Moving and stationary contacts are front accessible, simplifying inspection and maintenance
• Reliable U-shaped magnet for reduced power consumption
• Coil design reduces inventory/maintenance expenses. For a given voltage, one size coil fits all contactors Sizes 00–2, and a second coil fits threepole 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.

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 hp

These AC magnetic contactors utilize clapper design and feature straight-through wiring.

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 life.

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.

Panel layout and drilling are simplified through the use of common backplates, one for Sizes 00–2 and one for Sizes 3–4.

Latched Design

This is a mechanically held, electrically released device. It is applied where the contactor must remain closed during extreme voltage fluctuations or power failure.

DC Operated

This device is DC operated. It is used where low dropout voltage or exceptionally quiet operation is desired.

Size 7, 900A, 600V, Open | Size 8, 1350A, 600V, Open | Size 9, 2500A, 600V, Open

Class A201 Size 7 and 8 contactors are DC operated side clapper design with the shaft mounted on dual needle bearings to ensure positive contact alignment and long contact life.

Application Description

Magnetic contactors are used to switch transformers and capacitors and to control electrical power circuits.

Standards and Certifications

A201 contactors are UL listed components and also have CSA certification.
