RITTER slide-in Switchgear type GT4D

12 kV compact switchgear with double busbar system, circuit-breakers with draw-out or fixed mounted design and busbar connectors or load-break disconnectors.


  • IEC 62271-200
  • up to 24 kV, list 2
  • up to 3150 A and 31,5 kA 3s
  • air insulated
  • metal enclosure, metal clad
  • Arc fault tested IAC AFLR


The GT4D switchgear is the most compact air-insulated double busbar switchgear in slide-in technology on the market. It covers a wide range of technical requirements. Due to the compact dimensions and the space-saving integrated pressure relief channel (optional), the system is also ideal for retrofit measures in small, tight control rooms. For the components used, such as protection and circuit breakers, we can react flexibly to customer requirements.

Field of Application

Circuit-breaker switchgear can be used for distribution substations in grid-, industrial- and power supply plants and are applicable for the switching of transformers, motors, generators, capacitors and transmission lines.


Metal enclosed, air insulated, factory assembled and type tested. Compartmentalization is made between the cubicles as well as between busbar-, slide-in and cable compartment sections. Highest personal and operational safety through the availability class LSC2B. Classification for internal errors IAC AFLR.

Panel Types

Incoming feeder, outgoing feeder, metering- and busbar coupling; bussection- and busriser panels with motorized loadbreak panels with motorized loadbreak switches and withdrawable circuit breakers.
