Abstract

La presente invención se refiere a un aparato indicador de condición de fusibles adaptado para ser conectado a un circuito eléctrico polifásico cuyo circuito eléctrico incluye una pluralidad de conductores en línea, correspondiendo a conductores de corrientes y fusibles lo que cada fusible es conectado en serie entre la correspondiente línea y conductores de corriente, componiéndose dicho aparato de: Un indicador plural cada uno para producir indicaciones para reconocer la condición de un fusible correspondiente. Un primer aparato resistor plural el cual es adaptado para ser conectado entre un lado del indicador y por el otro lado del correspondiente fusible; dicho primer aparato resistor sirve para proveer un conductor substancialmente resistente. Un segundo aparato resistor plural el cual es adaptado para ser conectado entre un lado del indicador y un lado del fusible, dicho segundo aparato resistor se usa para proveer un conductor substancialmente resistente. Un tercer aparato resistor que está conectado entre los otros lados del indicador para proveer un conductor substancialmente resistente entre los otros lados del indicador.
