GAF1250 ... GAF2050 3-pole contactors

1040 to 1750 A DC-1
AC / DC operated with 1 N.O. + 1 N.C. auxiliary contact

Description
GAF1250 ... GAF2050 contactors are designed for controlling resistive or slightly inductive loads up to 1000 V DC.
These contactors are of the block type design with 3 main poles for connection in series by the user accord-
ing to conductor cross-sectional area or by using LP connection bars to be ordered separately.
– main poles arc chutes fitted with permanent magnets specially designed for DC breaking. The connection
polarities must be respected.
1SFC101004F0201 (e.g. 100...250 V AC and DC), only 4 coils to cover control voltages between 48...500 V 50/60 Hz and
– control circuit: AC or DC operated with electronic coil interface accepting a wide control voltage range
24...500 V DC
- can manage large control voltage variations
- reduced panel energy consumption
GAF1250-10-11 - very distinct closing and opening
- can withstand short voltage dips and voltage sags (SEMI F47 conditions of use on request).
– built-in surge suppression
– add-on auxiliary contact blocks for side mounting and a wide range of accessories.
