Low level of equipment variation due to easy convertibility of cable feeder at top/bottom (delivered from factory with cable feeder at bottom)
Only one device variant for applications in industry and infrastructure thanks to touch and reach-around protection as a standard feature.
Uniform grid sizes for easy configuration.
Advantages during operation and service
The optional rear covers for the cable connections ensure optimum touch protection even for distribution boards with access from the rear.
Innovative design enables the highest safety for equipment and personnel.
Fuses can be released and removed using a release shaft.
Lockable and sealable design enables safe working and prevents unauthorized access.
Advantages during installation
Only one device version is required for cable feeders at top/bottom and there is no need to intervene in the internal conducting paths.
One device variant with very high short-circuit values dispenses with having to order and install arc splitters to increase the electrical values.
On all sizes it is possible to install two CO contacts for indicating the switch position.
All devices feature all-round touch protection.
Box terminals are available for all sizes and shorten the mounting time appreciably.
Snapping on the sizes NH000 and NH00 shortens the mounting time greatly compared to fixing with screws.
The screw-fixing method on sizes NH1, NH2 and NH3 provides for easy positioning and at the same time secure contacting of the larger and heavier device variants.
Small space requirement through compact devices and busbar supports which can be built over.
Device variants for busbar mounting can be converted to 5 mm or 10 mm thick busbars without parts which can be lost or broken off.
