MV-C®

630–2,500 A and 3.6–17.5 kV


MV-C® Basic design

The innovative, type-tested, air-isolated medium voltage switchgear system IGEL® MV-C can be used for a wide range of applications from modern drive concepts to complexe energy distribution systems.

The medium voltage switchgear system MV-C is approved according to DIN EN 62271-200 (VDE 0671200). This test confirms the standard arc classification IAC AFLR 40kA 1s and is made to proof the protection of the operators (access classification – type A / Access only for authorized personnel).
The MV-C system is approved with loss of service continuity category LSC 2A as
well as partition class PI and by this partial isolated switchgear system. The power units can be switched into a test- / disconnected position. In this position the automatic metal shutter will be pivoted in front of the moving contacts so that the accidental protection for the busbar section is granted. The separation for fire protection is very effective in case of an internal arc in the cable/device section. From the accidental protection point of view the system is separated into 3 (2/1) sections:

– Busbar section (optional)
– Low-Voltage section
– LS-/Transformer-/Cable connection section

This switchgear system is designed for indoor installation in electrical control rooms. The MV-C system is from galvanized/ painted steel in stable heavy duty construction and separated into four metal clad sections (Low voltage part, busbars, MV section and cable connection unit). All units can be combined and lined up as required.

The MV-C system is characterized by an easy and quick installation for the switchgear type A without decompression channel in a room with a height of 2.80 m. The installation has to be effected on an iron frame or raised floor.
The busbars will be combined with each other using connecting clusters which are included in our delivery.
Only appropriately qualified and trained personnel is authorized to do the
commissioning and maintenance on this equipment. All maintenance and safety guidelines according to DIN/VDE as well as the a cident prevention & insurance association have to be observed.
