AC Switchgear (Indoor)


Highly trusted, air insulated indoor switchgear for primary and secondary power distribution applications


Appreciated throughout the distribution network, the Eclipse currently holds a leading market position for indoor 11kV switchgear.

The fixed pattern design has the simplicity of air insulation and, with the low parts count (the total parts count has been reduced by a factor of x20 and the number of moving parts by a factor of x50), is more compact (500mm wide) than equivalent rated GIS equipment.

The Eclipse boasts superior operator safety with a fully interlocked disconnector selector mechanism, animated front panel mimic and a front access cable test facility, eliminating the need for any intrusive access to high-voltage compartments.

The Eclipse is certified to IEC62271 and available as a pre-engineered solution in ratings up to 25kA, 2000A. Alternatively, it can be fully engineered to customer requirements.
