Compact SKS EnergyLine MU 20 metering panel
Type tested according to the DIN EN 62271 200 standard for safe and reliable use in the power distribution grid
Description
The compact SKS EnergyLine MU 20 metering panel is type tested according to the current DIN EN 62271 200 standard and thus meets the requirements for safe and reliable use in the power distribution grid.
The internal arc fault containment of the metering panel was successfully verified according to IAC AFL 20 kA for 1 second in a certified testing facility.
The metering panel is developed and designed for use under normal operating conditions in accordance with DIN EN 60694 and can be installed in compact substations thanks to its design.
Construction
The metering panel consists of a modular sheet steel construction. The individual elements are connected using sheet steel.
The front enclosure is formed by a pressure resistant sheet steel panel while both side walls and the rear wall are also made of sheet steel.
The busbars are made of 40 x 10 mm flat copper.
Cables that would be connected are fed into the measuring field from below and can be securely fastened there using variable cable retaining clips.
Technical equipment
The metering panel accommodates the installation of standardized current and voltage transformers.
Optional equipment
The separate instrument compartment can be equipped with various measuring devices, fuse elements, and other components.
We would be happy to present additional configuration options upon request.
