Abstract
A quenching plate arrangement for a switching device has plural quenching plates for arc splitting and/or lengthening; a guiding plate, the quenching plates being arranged substantially next to one another to firm a stack, the guiding plate laterally delimiting the stack, the guiding plate protruding beyond the quenching plates in a main extension direction; and a DC-suitable switching device having a first contact and a second contact, at least the second contact being movable relative to the first contact, a first and second running rail arrangement for conducting an arc with respective first and second current directions, the two running rail arrangements having respective first and second running rails, the two first and two second running rails respectively running in opposite directions from the first and second contacts, and the first running rails being connected in an electrically conducting manner in closed loop form, with the quenching plate arrangement.
