Abstract (en)
[origin: EP2573789A1] The switch has a housing, and two switching device areas (1, 3) arranged in the housing. A quenching chamber device (5) and a sliding contact device (7) are arranged in one of the areas. A current release assembly consisting of a short-circuit trip (17) and an overload trip (26) is arranged in another area. A continuous ventilation channel (33) is formed within a housing wall along fixed contacts (10), where the channel acts as a convective air-flow through the power switch for dissipating heat. Movable contacts (9) are positioned opposite to the fixed contacts.
