PERFECCIONAMIENTOS EN UN INTERRUPTOR ELECTRICO CON PANTALLA

摘要

A screened electric switch in which the screen is inserted at high speed between the contacts and in which a mobile shutter with a sealing surface basically fixed relatively to the housing drives the screen with a speed which is a function of the energy of the arc. This switch is applicable to circuit breaking devices designed to check the rise of short-circuit currents or high steady-state rated currents.
