Applications

ABB welding isolation contactors are suited

to the rugged demands set forth by the
automotive industry and are specifi cally
designed for use in high current welding
applications. ABB is the leading contactor
supplier for automotive welding applications.

Features

• Includes sizes:
– W3 thru W6 in 3 pole confi gurations
– W4 thru W5 in 2 pole confi gurations

• Unique contact design assures reliable and safe
operation during high current welding cycles

• 1 N.O. & 1 N.C. auxiliary contacts are standard
and up to 6 additional auxiliary

contacts may be added to provide a total of
8 (4 N.O. & 4 N.C.)

• Easy front removal of arc chute for quick
inspection and change of contacts

• Operates over an extended voltage range of 85%
to 110% of rated control voltage

• UL Listed, File # E79416

• CSA Certifi ed, File # LR19700

AW welding isolation contactors can save
substantial space compared to other conventional
contactors.

Coil voltage selection – wide range AC/DC coils for
AF contactors

All AC operated catalog numbers include a 100-250 V AC/DC coil. To select other
coil voltages, substitute the code from the Coil Voltage Selection Chart for the
two digits after the last dash in the catalog number.

Ex.: A 24V coil is required for a AF460W contactor: AF460W-30-11-68

Coil voltage selection – A contactors

All AC operated catalog numbers include a 120VAC coil. To select other coil
voltages, substitute the code from the Coil Voltage Selection Chart for the two
digits after the last dash in the catalog number.

Ex.: A 240V coil is required for an A75 contactor: A75-30-11-80

Auxiliary contact blocks

For additional auxiliary contact blocks, see catalog number explanation on page

1.2. Add $ 20 to list price for each additional auxiliary, and see page 1.18 for
available combinations.
