SIVACON S4 to 3200A

As type-tested switchgear, SIVACON S4 stands for maximum reliability
and a high degree of safety. High quality, perfectly matched switching
devices facilitate an easy integration in the building control technology
concept thanks to the system’s outstanding feature: built in intelligence.

During operation, an efficient ventilation system prevents heat
accumulation and heat pockets, thus assuring long term system
availability.

A fast and easy access to the devices for setting purposes is facilitated
through doors with central locking, swivel frames and quick release locks.

Thanks to the enormously powerful locking system, maximum personal
safety is even guaranteed in fault cases. Forms of internal separation 1,
2b, 3b, 4a and 4b are available.

The Powerstar 125 and 250 range of panelboards are suitable for Polestar Compact
wall/floor mounting and are available in three busbar sizes. A 25kA, 250A
busbar system, a 35kA, 400A busbar system and a 50kA, 630A system
provide solutions for either main or sub main distribution requirements
within a broad range of commercial and industrial applications.

Integral incoming metering can be applied to any of the main units while
metering cableways accept meters for outgoing circuits. Lightning and
surge arresters can also be included as an integral option.

Meter kits and surge protective device kits are available which fuse links,
fittings, cable looms and the device itself. Powerstar 250 panelboards
are complete with fixed busbar assemblies, incoming switching unit and
are fully type tested to BS EN 61439-2.

Powerstar 250 circuit protective MCCBs consist of a TP switching unit
and overcurrent release providing a choice of characteristics.

Three available overcurrent releases will provide sixteen increments of
thermal overload release and two short circuit release settings. In total,
ratings of between 40A and 250A are catered for.

Switching units are available at 36kA and 65kA. In addition, GG frame
MCCBs, fixed magnetic/fixed thermal can be used in Powerstar 250
add-on units to provide both SP and TP options of between 15A and

Polestar Compact to 250A

Designed and manufactured in the UK, the Polestar Compact range of
distribution boards offers the contractor and specifier a comprehensive
package to address the demands of modern commercial installations.

Type B three phase distribution boards are suitable for wall mounting and
are available in two busbar sizes. A 125A and 250A busbar system is
suitable for use as sub or final distribution within both commercial and
industrial buildings.

All type B distribution boards offer an integral metering facility. This means
no increase to the overall footprint and so whilst retaining generous
cabling room, Polestar Compact distribution boards accommodate even
the tightest of riser cupboards.

Also available are Type A distribution boards. Both Type A and B
distribution boards are supplied complete with fixed busbar assemblies
and are fully type tested to BS EN 61439-3, utilising a sheet steel
enclosure finished in light grey paint (RAL 7035).

Ingress Protection is IP3X throughout the range. MCBs are 16kA
protective devices which have an 18mm modular width available as SP,
DP and TP with tripping characteristics B, C or D. RCBOs are available
as SP single module with tripping characteristics B or C.
