Overvoltage protection

New from Wieland, the latest wietap
range of overvoltage protection
modules reflects the
growing need for
effective overvoltage
protection of
machines, systems
and building
technology. The
wietap range is
designed to provide
a complete protection
system for the building, from Type 1
arresters on the building’s mains
supply, through to Type 2 and 3
arresters in sub-panels and control
cabinets.

Crucially, wietap modules deliver
a very short response time and high
discharge capacity (up to 100kA),
with no tripping of fuses thanks to
the ‘follow current limitation’. They
are designed for use in control
cabinets, and sub-panels of
machines and buildings,
as well as photovoltaic
systems.

All components
are modular and DIN
rail mountable and
can be replaced
without tools. They range
from the ready-to-connect 3-
phase combi-arrester wietap V M for
the main distribution and wietap G
M for sub-panels through to wietap
R M for control cabinets or
integration into equipment.
