RDH5(HGL) series load isolating switch (hereinafter referred to as the switch) is suitable for AC 50Hz, rated voltage up to 660V, DC rated voltage up to 440V, rated current of 125A-1600A, in the distribution system for non-frequent connection and disconnection of circuits and isolation circuits, of which 1000A above switches only do electrical isolation. The switch has a glass fiber reinforced unsaturated polyester resin housing: the spring energy storage acceleration mechanism can quickly realize the connection and disconnection, the contact structure is a parallel double break two separated contact surfaces, and the sheet spring guarantees the contact pressure; The switch can automatically determine the limit position of the on-off and has a clear on-off mark to indicate the on-off position.
The RDH5(HGL) series load isolation switches are designed for use in AC circuits up to 660 V, with rated currents ranging from 125 A to 1600 A. They are suitable for environments up to 2000 m altitude and temperatures from –40 °C to +140 °C.
Key features include fast make/break operation, clear on‑off indicators, and an automatic reset function. The document contains dimensional data, wiring diagrams, safety notes and detailed installation procedures for both side‑mount and front‑mount configurations. This manual is written in Chinese.
