Abstract (en)
[origin: EP2390890A1] The arrangement has a bar assembly (100) provided with a set of bars (10-40), where each bar includes base areas (11, 13, 21, 23) and central areas (12, 22) lying between the base areas. The bars are arranged around a longitudinal extending axis (L) of the bar assembly along a periphery (U). The bar assembly includes two mechanical coupling regions (101, 103) present on a side of the respective base areas for coupling to respective switch contact poles of a circuit-breaker. Each bar exhibits an elongated cross-section within the central areas. An independent claim is also included for a circuit-breaker comprising a field control cover connected with a switch contact pole.
