This manual introduces the product features, technical parameters, product structure, installation, use and maintenance of MC1-100/160/400/630 type AC contactors in detail.
The specification sheet details the electrical ratings of the RDM10 moulded case breakers, including enclosure class, rated current ranges, rated voltage, short‑circuit breaking capacity, and arc distance limits. It also describes the control and auxiliary circuit requirements, as well as the operating mechanism and conditions for both distribution and motor protection applications.
Additional tables list test current values, coordination with protective devices, and performance characteristics such as breaking and making capacities under various voltage and temperature conditions. The document is intended for engineers and technicians responsible for selection, installation, and maintenance of these breakers. This manual is written in Chinese.
