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
the switchboard.
- 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
live cables.
