Contactors--Non-Reversing and Reversing

 

Non-Reversing

Contactors are 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.

 

Reversing

Reversing 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.

 

 

Features, 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

Product Description

 

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

  • Relaible 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 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 323.

 

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.

 

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 contactor operation.

 

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 are available:

 

  • 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. 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

  • DC Operated--

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 contact


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.

 

A steel panel base permits mounting on angle or channel without additional support for versatile low cost installation.

 

Each stationary contact assembly is mounted on an individual molded insulator. Each pair of contacts is surrounded by a De-ion grip type arc quencher for rapid and confined arc interruption and long contact life.

 

The shunt for each pole is made of flexible, braided copper cable for freedom of movement and long life.

 

The rugged DC operating coils are designed to operate at high temperature and insulated to meet Class H service.

 

An integrally mounted avalanche type silicon rectifier supplies DC coil voltage from the AC control circuit.

 

Sizes 7 and 8 accommodate three Type L-63 auxiliary contacts which are easily converted from normally-open to normally-closed, providing auxiliary circuit flexibility. Size 9 uses L-64 auxiliary contacts with a total of four circuits.

 

A201 Size 7, 8 and 9 contactors and starters are UL recognized when supplied without terminals. When supplied with terminals, the devices are UL listed.
