HR6 series molded case circuit breaker is mainly used for rated voltage AC380V and 660V (45~62Hz), rated thermal current up to 630A, with high short circuit current distribution circuits and motor circuits, as power switch, isolating switch, emergency switch and circuit protection, but generally not used to open and close single motor directly.
This manual describes the HR6 series fuse type isolating switches, which are intended for use in AC 380 V and 660 V distribution circuits with heating currents up to 630 A. It covers the switch’s rated voltages, short‑circuit capabilities, environmental limits, and the relationship between the switch and compatible fuse types.
Installation details include the plastic construction, mounting hole patterns, auxiliary contacts, and the procedure for replacing the fuse cartridge. The document also lists ordering requirements such as type features, voltage level, current rating, pole number, operation mode, and quantity. This manual is written in Chinese.
