The Eclipse is designed to provide a lifetime of unrivaled service, bringing together one of the most advanced operating mechanisms available on the market today – the award winning magnetic actuator technology. Appreciated throughout the distribution network and across every business sector, the Eclipse currently holds a leading market position for indoor 11kV switchgear.

Key Features

Superior technology with minimal maintenance

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 of 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 meet exact customers needs

Endurance tested to 10,000 operations

Environmentally friendly vacuum interrupters

Internal arc containment

Voltage Presence Indication System

(VPIS) is fitted as standard to all panels (circuit)

Award-winning magnetic actuator technology powered from substation battery via contactors

Trip circuit supervision, self diagnostics & position indication contacts included as standard
