– A load-break switch or circuit breaker
must be included in the electrical
installation of the building.
– It must be installled close by the
equipment and within easy reach of the
operator
– It must be marked the disconnecting
device of the equipment:
IEC/ EN 61010-1 § 6.11.2.
This equipment must be installed by
qualified personnel, in compliance with
regulations in force for electrical systems, to
avoid damages or safety hazards.
The pfoducts, illustrated in this document,
are subject to be revised or improved at any
moment. Technical data and descriptions do
