Abstract

Dispositivos interruptores de circuito tienen un primer alojamiento con un interruptor de circuito, un segundo alojamiento acoplado al primer alojamiento, un circuito de falla a tierra y transformador de corriente en el segundo alojamiento. El transformador de corriente tiene un canal abierto. Los dispositivos interruptores de circuito incluyen también al menos un conductor de energía que tiene un cuerpo rígido o semirrígido con primera y segunda porciones de extremo que se extienden entre el primer y segundo alojamientos. La segunda porción de extremo del al menos un conductor de energía se extiende a través del canal abierto en el transformador de corriente y termina en un(os) collarín(es) interruptor(es) de carga.
