complete
A carefully studied and complete line ranging
from 16A to 100A with emergency control
versions. They are also equipped with
auxiliary contacts for remote indication of
main contacts position.
multi-purpose
Due to its modular dimensions with TER
Series interlocked industrial socket-outlets,
they can also be installed in multipurpose
assemblies, or singularly wall-mounted
or machine-mounted.

UNBEATABLE
An AC23A – AC3 installation class, conditional short circuit current 10,000A
and guaranteed isolation are but a few of
the superbly performing features of the
isolator switches. At the maximum level of
what the market offers today, they allow
direct control of even highly inductive
loads (such as pumps, exhaust fans,
mills, compressors, etc.) and eliminate
costly machine shutdowns with a subsequent increase in the installation’s yield.
NO DOWNGRADING
In addition to making wiring easier, the
spacious interior ensures maximum
thermal dissipation thereby eliminating
downgrading and premature ageing.
As a consequence provides ample cabling
and glanding space.
MULTIPURPOSE
May be integrated with TER Series
distribution boards which allow
multipurpose batteries to be created for
direct control of each service or as a battery
main switch.
MODERN
With the knob inserted in the front panel,
the packaging meets the most demanding
aesthetic needs and reduces the ingress
of grime and dirt. This makes the product
ideal for areas subject to inspection. The
ergonomic knob makes operating with work
gloves easy.
