GF875 ... GF1050 contactors

875 to 1050 A DC-PV3
AC / DC operated with 2 N.O. + 2 N.C. auxiliary contacts

GF875 ... GF1050 contactors are specifically designed for 1500 V DC PV solar central inverters.
These contactors are of the block type design with 2 main poles. The main poles are fitted with
03
special arcing contacts enabling bi-directional breaking of currents up to 750 V DC per pole.
• control circuit: AC or DC operated with electronic coil interface accepting a wide control
voltage range (e.g. 100...250 V DC), only 2 coils to cover control voltages between
24 V AC / 20 V DC ... 60 V AC / DC and 100 ... 250 V AC / DC.
- can manage large control voltage variations
- reduced panel energy consumption
- very distinct closing and opening
- can withstand short voltage dips and voltage sags.
• built-in surge suppression
