ROUND UP
Integrated electrical system
GEWISS, represented locally by ACDC
Dynamics, produces systems and com-
ponents for low voltage electrical installa-
tions globally. The fact that development
is seen as a constant management feature
has permitted GEWISS to assert itself as a
market leader, offering an integrated elec-
trical systemwith over 20 000 products for
Domotics, Energy and Lighting.
Gewiss’s protection system is com-
posed of products which have synergy
and perfect integration among each other,
such as the innovative 90 ReStart range
(automatic reclosing devices), the 90
MCB and 90 RCD ranges (modular circuit
breaker for circuit and residual current
protection) and the 47 CVX range (metal
distribution boards). An integrated range
of products which can meet every need
according to the application type, from
residential to the industrial and which can
guarantee quality and safety in step with
market requirements. The advantages
of GEWISS system are several, practical
compatibility of homogenous products,
simple and quick planning, installation
and maintenance of the system, as well
as modern and stylish design. 90 ReStart
devices restore power supply quickly
from automatic circuit breaker trips, but
only after checking the system status. In
addition, the Autotest function periodi-
cally tests the functioning of the residual
current circuit breaker protection without
disconnecting the system from the power
supply. The range includes two pole and
four pole versions.
The 90 RCD range includes the MDC
monobloc compact residual current circuit
breaker with overcurrent protection, the
BD and BDHP add-on modular residual
current devices for MT and MTHP minia-
ture circuit breakers and the SD residual
current circuit breaker.
The 90 AM range consists of auxiliaries
for circuit breakers and many modular
accessories for protection, command,
programming, measurement and signal-
ling in electric systems.
The LST surge protection range guar-
antees excellent protection of loads and
power distribution systems. The 47 CVX
range of distribution boards is available in
bothmodular andmonobloc systems from
160 A to 3 200 A. In both surface or flush
mounting types, these boards are avail-
able in a variety of IP ratings to suit most
applications. Thanks to the extractable
frame and quick connection of brackets,
rails and functional profiles, the 160 A
board allows quick assembly. Because the
630 A boards are based on a ‘completely
open structure’, board wiring operations
are quick and easy.
