IV2000-20~32 12/17.5 kV

The IV2000 is an advanced vacuum switchgear system featuring permanent magnet actuator drives, the use of self-powered digital protection relays requiring no external auxilliary power supply, and power sensors such as rogawski coils. It is a small switchgear of superior performance and reliability suitable for a wide variety of applications.

General features include: Nominal current until 1250A. Max breaking capacity till 31.5 kA, Short-circuit withstand capability at (rms) 20~31.5 kA/4sec Minimum Panel Dimensions (mm) 520X950X1700 (WXDXH)
