Advantages during planning and configuration

• 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.
