Application
AL..ST, AL..Z..ST and TAL..ST contactors are the spring terminal version of AL-range.
The ST-range of contactors use ABB Entrelec's proven spring terminal technology giving the following benefits:
Description
The AL..ST series 3-pole contactors are of the block type design.
The AL..Z..ST series 3-pole contactors are of the block type design with a very low coil consumption of 2.4 W.
The TAL..ST series 3-pole contactors are of the block type design with a large coil voltage range.

a fast connection on the front face, which saves labour time,
vibration proof,
no need to retighten the terminals saving maintenance labour time.
Main poles and auxiliary contact blocks
AL..ST, AL..Z..ST, TAL..ST 1-stack contactors:
– 3 main poles,
– coil terminals,
– front mounted add-on auxiliary contact blocks.
Control circuit: d.c. operated with solid core magnet circuit and low consumption
coil. The coil must be energised from a d.c. supply and the polarity (+ and -) must
be respected.
Accessories: a wide range of accessories are available.
Connection: the cables are connected via the front face with the possibility to use
two different types of cables with different cross-sections.
