Specifications of DB25/25A

• Svhc: No SVHC (18-Jun-2010)

Application
AL.., AL..Z.., TAL.. contactors are mainly used for controlling 3-phase motors and more generally for controlling power circuits up to 690 V a.c. or
220 / 440 V d.c. These contactors have a low power consumption for direct control from PLC outputs. Consequently they are perfectly adapted for
all applications associated with PLC control.
Description
The AL.. series 3-pole contactors are of the block type design.
The AL..Z.. series 3-pole contactors are of the block type design with a very low coil consumption of 2.4 W.
The TAL.. series 3-pole contactors are of the block type design with a large coil voltage range.
Variants
Low Voltage Products
Main poles and auxiliary contact blocks
AL 9 ... AL 40 1-stack contactors:
– 3 main poles,
– 1 built-in auxiliary contact,
– front or side mounted add-on auxiliary contact blocks.
AL 9 ... AL 40 2-stack contactors:
– 1
– 2
The built-in auxiliary contact elements are mechanically linked
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.
