A 9 ... A 110 3-pole Contactors

a.c. Operated

Application

A 9 ... A 110

contactors are mainly used for controlling 3-phase motors and generally for controlling power circuits up to 690 V a.c. / 1000 V a.c. or

220 V d.c. / 440 V d.c. The contactors can also be used for many other applications such as isolation, capacitor switching, lighting.

Description

The A... series 3-pole contactors are of the block type design.

●

Main poles and auxiliary contact blocks

A 9 ... A 40 1-stack contactors:

–3 main poles,

–1 built-in auxiliary contact,

– front and side mounted add-on auxiliary contact blocks.

A 9 ... A 40 2-stack contactors:

–1st stack with 3 main poles and 1 built-in auxiliary contact,

–2nd stack with 4 built-in auxiliary contacts,

– side mounted add-on auxiliary contact blocks.

The built-in auxiliary contact elements are mechanically linked.
