Abstract

La presente invencion se relaciona con un circuito de proteccion eléctrica que comprende un fusible eléctrico, que incluye una soldadura (3), y un circuito de resistencia eléctrica (10) conectado en serie con el fusible (1), el fusible y el circuito están montados en un substrato (11). La soldadura (3) se fundirá a temperaturas elevadas provocadas por el calentamiento del substrato (11), y está rodeado por un material (8) que protege a la soldadura (3) contra el efecto oxidante del aire circundante, y está aplicado en una region (9) que rodea a la soldadura (3) estando delimitado mediante paredes de barrera (7), haciendo posible con esto que cuando la soldadura (3) se funda, se contraiga sobre las terminales de conexion (4a, 4b), interrumpiendo así la trayectoria de la corriente. El material (8) es termoestable en estado solido a las temperaturas normales de operacion del fusible. El circuito de resistencia (10) incluye trayectorias conductoras de corriente (12) conectadas mutuamente con elementos de puente (13) cuya resistencia eléctrica es mucho menor que la resistencia eléctrica de las trayectorias conductoras de corriente (12) y elementos de corte (14) para ajustar la resistencia del circuito.
