Wind and Solar Power Inverter Controlled System Vacuum Contactors

Greegoo GVC9 series vacuum contactors are specifically designed for very high current ranges from 800 A to 1,400 A. With their electronically controlled drives, compact size and long service life, the contactors make for a reliable component in any machine and system.

Our GVC9 contactors can be used for disconnecting networks, in inverter-controlled systems and for controlling inductive loads that are not switched on or off.

They are also designed for switching loads such as heating or distribution systems and loads in accordance with utilization category AC-1 as per IEC 60947-4-1.


Utilization category AC 1 and AC 3
Suitable for up to 1,000 V
AC/DC wide-range coil
Low holding power
Compact size, space saving of electrical switch cabinet
Auxiliary contacts: three NO, three NC
Significantly less heating of switch cabinet
Longer service life of the switching contacts
A tighter arrangement of the switchgear is possible

Recommend to use in wind and solar power inverter controlled system.
