the Zucchini Super Compact range is manufactured in accordance with
national and international regulations as shown below:
The SC range
has Conformity Certificates produced by the most prestigious international
The SC external casing is in hot-galvanised steel sheet treated
in accordance with EN 10142 regulations, it has a thickness of 1.5
mm and is shaped in such a way as to give excellent electro-mechanical
characteristics and heat dissipation.
On request, version in hot-galvanised steel sheet are available,
painted and/or with an aluminium frame.
The casing comprises four steel "C" - shaped profiles,
assembled by means of crimping and riveting.
The frame is totally enclosed (without ventilation holes) and guarantees
total safety against contact with live parts.
The Super Compact range has a standard protection rating of IP55
(IEC 529) and therefore resistant to the ingress of dust and water.
However, for outdoor installation it is advisable to install a cowl
offering extra protection.
the conductor bars have a rectangular section with rounded corners
and are available in two versions:
copper ETP 99.9 UNI 5649/65
AD 14 UNI 3570 galvanically plated along the entire surface
form an insulated sandwich construction and are fully insulated
using a double sheath of Class "F" polyester insulation
(0.19 mm thickness).
Jointing: the electrical
and mechanical jointing of the trunking elements is achieved by
a simple monobloc system; the monobloc joint is tightened using
a double headed torque bolt which ensures that the required contact
pressure on the conductors is maintained.
The correct torque setting is achieved when the outer head shears
at a pre-set torque level (Cmax = 85 Nm).
The mechanical joint of the busbar trunking is completed by screwing
into place the cover plates which guarantee the IP rating.
When the SC is installed as a double bar configuration (from 3000
A and above for copper conductors, and 2500 A for aluminium) the
joint block joins in parallel the same phases in each casing thus
balancing the current.
the Super Compact system offers a full range of trunking accessories
including horizontal and vertical elbows, T-elements, double elbows,
which gives total flexibility throughout a project.
tap-off units are available as bolt-on units at the joints of the
elements in ratings from 125 A to 1250 A; in either case the tap-offs
can be supplied fitted with fuse switches or circuit breakers as
Tap-off units from 125 A to 400A ratings are also available as plug-in
units which can be inserted and removed from the busbar while the
system is live.
the suspension brackets clamp around the Super Compact frame and
create an anchoring point on the bracket support (these latter ones
may be supplied on request by Zucchini S.p.A.).
The maximum fixing distance for the Super Compact is 2 m; Zucchini
recommends, in normal conditions, an optimum fixing distance of
accessories (on request): special elements are available for connection to
switchboards and transformers, complete with straps, flexible joints
and protection boxes if needed.
When passing through walls a fire barrier is available for positioning
outside the trunking in order to reinstate the fire-resistance of
Fire barriers are not required inside the casing as Super Compact
has a sandwich configuration which prevents the circulation of air
inside the casing and all plastic materials used are self-extinguishing
and non fire-propagating.
The SC range also has all the accessories required for installation
of vertical system for use as rising mains.
