Benefits
-
Enhanced touch protection
-
Locking and sealing function helps to prevent unauthorized operation
-
Small space requirement through compact devices and busbar supports which can be built over.
-
Modular design
-
One device version with very high short-circuit values dispenses with having to order and install arc splitter chutes to increase the electrical values.
-
All devices feature all-round touch protection.
-
Box terminals are available for all sizes and shorten the mounting time appreciably.
-
Snapping the sizes 000 and 00 onto a busbar shortens the mounting time greatly compared to fixing with screws.
-
Devices for busbar mounting can be converted to 5 mm or 10 mm thick busbars without parts which can be lost or broken off.
