1.2 Product description
1.2.1 General
The low voltage-fused-switch disconnector system 403 has been specially designed and manufactu-
red to meet the requirements of our customers. They have been in trouble-free use for years.
The correct choice of busbars and components is the responsibility of the operator and operator of the
new standard IEC or DIN EN 61439 describes as a successor standard to DIN EN 60439 the design
and inspection specifications for low-voltage switchgear combinations, where planning, construction
requirements and the required type-approvals are prescribed. In order to safely eliminate hazards for
people and goods when handling electrical energy, the expert handling of the equipment and compli-
ance with the applicable regulations is generally required.
Installation and maintenance work, modifications and retrofitting may only be carried out by qualified
personnel in compliance with the general installation and safety regulations for work on power plants
(including 5 safety rules). The state of the technology and the impairments of the components among
themselves must be taken into account. In general, it is important to ensure that all touchable compo-
nents are switched off without voltage during maintenance measures.
In addition, it is necessary to ensure that the screw connections are made with the prescribed tighte-
ning torques, that the respective fittings are used and that the elements for contact protection are fully
available
The low voltage-fused-switch disconnector system shall be used and operated according to the inten-
ded use.
We would like to point out that the technical description in the product brochure as well as the assem-
bly instructions must always be observed and stored for maintenance work, modifications and retrofits.
Modifications for further development and technical progress are reserved.
