Auxigaine describes an extremely flexible and versatile system to set up individually adapted busbars. A modular system is used to provide rails with any number of poles. Standard length of up to 1.90 m permits use as permanently energised rail for the entire height of the switch boards. Every other dimension is possible as well, of course. Apart from a gigantic modular system, rails can be pre-wired for standard applications in the factory of the manufacturer. Auxigaine can be snapped on to a mounting plate as well as on to DIN rails using the mounting brackets intended for the purpose. Various conductors are available permitting the rails to be loaded up to 125A.
