A market leader in 12kV switchgear, the Eclipse is designed to provide a lifetime of unrivalled service, bringing together one of the most advanced operating mechanisms available on the market today – the award winning magnetic actuator technology – with vacuum interruption and the simplicity of air insulation in a compact, fixed pattern design.
Appreciated throughout the distribution network and across every business sector, the Eclipse currently holds a dominant market position for indoor 12kV switchgear.
Superior, proven Fit & Forget technology with minimal maintenance
The fixed pattern design had 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
Environmentally friendly vacuum interrupters
Internal Arc containment
Superior operator safety with a fully interlocked design, animated front panel mimic and a front access cable test facility, ensuring secure but simple operation
Voltage Presence Indication System (VPIS) is fitted as standard to all panels (circuit)
Reliable control – supplied with an integral control module, providing indication, trip circuit supervision and self-diagnostics

Eclipse Engineering Detail
Sleeved busbars constructed from hard drawn, high
conductivity copper, and vermin proof covered joints, 1
with normal current ratings up to 2000A. The busbar
arrangement permits future expansion, at either end of 2
Fully interlocked, manually operated 3-position disconnector including circuit earth and front panel cable
test access. The disconnector can be secured and 4
padlocked in all three positions: ‘on’, ‘off’ and ‘earth on/ test’, with its status indicated by animated front panel mimics.
A single moulding supports the three phase vacuum
interrupter assembly, magnetic actuator mechanism and 6
one-piece drive beam. 5
The patented single coil magnetic actuator mechanism is based on a solenoid plunger, held in the tripped or closed position by permanent magnets.
Three phase cast resin voltage transformer, with manually operated off-load disconnector on the primary circuit.
Generous CT accommodation enables complex protection schemes to be catered for in a single panel, whilst still allowing for a metering provision. The CT designs are rated in keeping with the short time withstand level of the equipment and comply with IEC 60044-1.
Unique Front Access Cable Testing Option:
Avoids any contact with Live cables or busbars.
Eliminates the need for Opening of rear covers to access live cables.
Provides secure & mechanically interlocked front access contacts points to connect cable test equipment.
Colour coded and suitably
labelled copper contacts
eliminates risk of improper
connections during testing
