Abstract
A vacuum interrupter having a structure to trap running cathode tracks is disclosed. The interrupter includes a first electrode assembly and a second electrode assembly, at least one of which is moveable. The interrupter also includes a sidewall having a longitudinal axis. One or more trench structures are formed in at least one of the electrode assemblies. Each trench structure has an opening that faces the other electrode assembly in a direction that is parallel to the longitudinal axis, to trap the running cathode tracks to prevent them from getting close to the sidewall.
