The RMW50 (DW50) series intelligent universal circuit breaker has a rated current ranging from 200A to 1000A. It is a compact and high-breaking-capacity circuit breaker with no arc distance.
The RMW50 Intelligent Universal Circuit Breaker is a low‑voltage device rated for currents from 200 A up to 1000 A (and up to 1250 A with expansion). It complies with GB14048.2‑2008 and IEC 60947‑2 standards and offers high breaking capacity and reliable protection against overload, short‑circuit, and ground‑fault conditions.
The manual covers installation limits (temperature +40 °C to ‑5 °C, humidity up to 50 % at +40 °C, altitude up to 2000 m), mechanical dimensions, wiring connections, and performance data such as short‑circuit breaking capacity (Icu = 42 kA at 690 V) and operating cycle ratings. It also provides adjustment settings for the intelligent controller and secondary circuit diagrams. This manual is written in Chinese.
