SGEAR series, metal clad cassette type switchgear is designed for primary distribution networks with the rated voltages of 12kV, 50/60Hz intended for indoor installation.

SGEAR series switchgear is air-insulated LSC2B-PM class, with single busbar design.

The switchgear concept meets today's owner requirements such as reliability, personnel and operational safety, economy and efficiency in an optimal way.

The switchgear is modular and is built up by placing standardized units side by side in a coordinated way. The Switchgear is easy to configure and selection of the apparatus and instruments does not imply dedicated solutions.

The functional units of the switchgear are guaranteed arc proof AFLR 31,5kA 1s in accordance with the IEC 62271-200 standard, appendix AA, class A accessibility, criteria 1 to 5. All the start-up, maintenance and service operations can be carried out from the front. The switchgear and the earthing switches are operated from the front with the door closed.
