1. Product Title

ABB 1YMB531029M0003‑ CMF Series Current‑Limiting MV Fuse Link

2. Product Overview

1YMB531029M0003 is ABB CMF‑series medium‑voltage current‑limiting fuse link, engineered for motor‑circuit short‑circuit and overload protection in 7.2 kV power distribution systems. Ceramic body with silver fuse element provides high breaking capacity to clear heavy fault currents rapidly, protecting medium‑voltage motors, transformers and switchgear assemblies. Complies with IEC 60282‑1 and IEC 644 standards for direct‑on‑line motor applications. This long cylindrical fuse is installed inside MV switch‑fuse cabinets, widely used as critical maintenance spare for power plants, substation and industrial medium‑voltage distribution systems.
