AF26Z ... AF38Z 3-pole contactors

4 to 18.5 kW
AC / DC operated for specific applications with 1 N.O. + 1 N.C. contacts

AF26Z ... AF38Z contactors are mainly used for controlling 3-phase motors and power circuits up to
690 V AC and 220 V DC. These contactors are of the block type design with 3 main poles (1st stack): 03
• 2nd stack with permanently fixed auxiliary contact block. The built-in auxiliary contact elements
are mechanically linked (side-marked symbol) and the N.C. auxiliary contacts are mirror contacts
• control circuit: AC or DC operated with electronic coil interface accepting a wide control voltage
1SBC101003V0014 range (e.g. 100...250 V AC and DC), only 4 control voltage ranges covering 24...250 V 50/60 Hz
and 12...250 V DC
- can manage large control voltage variations, allow direct control by PLC-output ≥ 24 V DC
500 mA, reduced panel energy consumption, very distinct closing and opening,
- can withstand short voltage dips and voltage sags (SEMI F47-0706 conditions of use on request).
AF26Z-30-11 • built-in surge suppression
• add-on auxiliary contact blocks for side mounting and a wide range of accessories.
