Abstract

Elemento de derivación limitador de corriente para disyuntores limitadores de corriente. Un disyuntor limitador de corriente compacto que está equipado con un elemento de derivación limitador de corriente, para la interrupción efectiva del circuito de sobrecorriente. La unidad de disparo de conmutación del disyuntor responde a condiciones de sobrecorriente de larga duración, corta duración e instantáneas, mediante la apertura de un conjunto de contacto, para aislar el circuito protegido Tras la separación de los contactos, se genera un arco, con los puntos extremos del arco dirigidos inicialmente al par de contactos abiertos. La apertura adicional de los contactos hace conmutar el arco dentro del elemento de derivación !imitador de corriente para redirigir la corriente fuera de la unidad de disparo de conmutación y suprimir la corriente de arco hasta que los contactos del disyuntor están lo suficientemente abiertos como para aislar el circuito protegido.
