Encapsulation to meet your needs
Beijer Electronics can supply frequency inverters in encapsulated format for mounting directly on the wall in factories, pump houses or offices.
With the correct encapsulation, installation can be in damp and dusty environments. No additional installations are necessary in cabinets.
Accessories such as servicing breakers, main switches and transitions from aluminium to copper cabling are easy to fit. If breakers for manual and automatic operation, multi-pump operation or other standard solutions are required, these can be supplied on request. We aim to offer flexibility and can supply encapsulation meeting the IP20, IP34 and IP54 requirements.
Encapsulation to meet your needs
IP20 encapsulation
For installation in technical rooms and installations to which only qualified staff have access. It is not possible to come into contact with electrically conductive material. Locked space.
IP34 encapsulation
For installation in most areas, such as production premises, offices and pumping stations. Whatever angle it may be, water sprayed on the cabinet cannot force its way in. Nor can particles larger than 2.5 mm enter.
IP54 encapsulation
For installation in areas such as production premises, offices and pumping stations. Whatever angle it may be, water sprayed on the cabinet cannot force its way in. Protects against dust.
Other standard arrangements, such as multi-pump operation, operation of several motors from one frequency inverter, etc. can be supplied on request.

Overview of sealing grades
Table showing an overview of the various IP classifications. We have only taken two of the figures in this review, but must say that there is a third figure as an option. The third figure refers to the entry of gases and is not normally needed.
