The RDM108 series moulded case circuit breakers are designed for AC 50‑60 Hz circuits with a rated voltage up to 660 V and a rated current range of 0.1 A ~ 63 A. They protect small‑capacity motors and wiring from overload and short‑circuit conditions and can be used for occasional line switching or direct motor starting.
The document details normal use and installation requirements, such as altitude limits, ambient temperature ranges, humidity limits, and pollution class. It also lists the main technical parameters, structural features, overload‑trip temperature compensation, protection characteristic curves, physical dimensions, and ordering information for the RDM108‑20, RDM108‑32, and RDM108‑63 variants. This manual is written in Chinese.
