Abstract

Un dispositivo de seguridad de emergencia portátil, para desactivar rápidamente un circuito de alimentación de energía eléctrica que tiene un conductor de fase, un conductor de neutro y un conductor de tierra y que tiene , conectados a los conductores, una pluralidad de receptáculos para recibir enchufes de conexión de aparatos eléctricos que han de ser activados por el circuito, y que está protegido por medios de interrupción de circuito por fallo a tierra de un valor predeterminado, cuyo dispositivo se caracteriza porque comprende un enchufe de múltiple espigas destinado a introducirse en uno de los receptáculos de manera que cada espiga de dicho enchufe quede eléctricamente conectada con uno de los conductores, y un interruptor manualmente operable, normalmente abierto, dispuesto en dicho enchufe y conectado eléctricamente entre la espiga para el conductor de fase y la espiga para el conductor de tierra, siendo tal la disposición que una corriente de fallo a tierra sustancialmente superior a dicho valor predeterminado se inicie en el circuito de alimentación de corriente cuando se introduce el enchufe en uno cualquiera de dichos receptáculos y se cierra dicho interruptor.
