| Zusammenfassung: | An elongated busbar board (1) for connection of devices (11) to a power busbar system comprises a front side touch protection cover plate (2) consisting of touch protection cover plate segments (2-i) made of an electrically insulating material and having feedthrough openings (7) for electrical connection contacts (13A) of devices (11) to be connected to the elongated busbar board. The touch protection cover plate is adapted to cover power busbars (6) made of an electrically conductive material having contact openings (5) lying directly beneath the feedthrough openings and comprises a touch protection base plate (3) connected to the touch protection cover plate and consisting of touch protection base plate segments (3-i) made of the electrically insulating material and adapted to cover the power busbars enclosed by the elongated busbar board from behind, wherein a thermal expansion difference caused by different thermal expansion coefficients of the electrically insulating material and of the electrically conductive material is compensated. |
