H01H33/901 - CPC Classification

Classification description:

High-tension or heavy-current switches with arc-extinguishing or arc-preventing means; Switches with separate means for directing, obtaining, or increasing flow of arc-extinguishing fluid the flow of arc-extinguishing fluid being produced or increased by movement of pistons or other pressure-producing parts this movement being effected by or in conjunction with the contact-operating mechanism making use of the energy of the arc or an auxiliary arc
