The moulded-case
circuit-breakers, proposed by ABB SACE, derive from two families of
apparatus: the well-known and consolidated Isomax S series and the
recent but already much awarded Tmax series (Top selection at Intel
Design 2003 for their technological content and respect of the
environment ). In particular, Tmax are characterised by an extremely
high level of performances with limited overall dimensions,
installation simplicity and an increasingly greater guarantee of safety
for the operator thanks to their reinforced insulation. Tmax
circuit-breakers, thanks to their performances, completeness of
protection releases and accessories, can be used for all distribution
and sub-distribution application for both AC and DC electrical plants.
Specific characteristics of Tmax
The
Tmax series is characterised by being a product with a high
technological content - the fruit of the most advanced design and
simulation tools with excellent performances in minimum overall
dimensions.
Thanks
to the new technology used for the arcing chambers and the speed of
contact opening, the circuit-breakers of the Tmax series guarantee
strong limitation of the specific let-through energy and reduction in
the peak currents, therefore limiting overheating of the devices and
electro-dynamic stresses.
Furthermore,
the new Tmax circuit-breakers use a completely common and standardised
range of accessories with considerable advantages in terms of reduced
stocks as well as flexibility and ease of use. Then within this range
there are also the new residual current releases up to 500 A.
Field of application
The
moulded-case circuit-breakers are used in industrial and civil low
voltage plants with service currents from 1 to 1000 A. They are used in
direct and alternating current distribution switchgear, for motor
protection (Motor Control Center), generators, capacitors and for end
users.
