HR6 Fuse-switch Disconnector

HR6 Fuse-switch Disconnector

HR6 fuse-switch disconnector (hereinafter referred to as the switch) is mainly used in the distribution circuit with high short-circuit current and motor circuit where the rated voltage is AC 380V and 660V (45 to 62Hz), the conventional thermal current is up to 630A  to serve as power switch, switch disconnector, emergency switch and exert the function of circuit protection, but is generally not used to directly open and close a single motor.
