Premium Soft Starter Cabinet 220V-660V 22kw-350kw

In the steelmaking workshops and blast furnaces of the metallurgical industry, the operating environment of dust removal fans (17kw-320kw three-phase motors) is extremely harsh: the workshop temperature often reaches above +50℃, the dust concentration is high, and the fan is under heavy load when starting (the resistance of dusty airflow is large). Traditional starting equipment is prone to tripping due to high temperature and dust blocking the heat dissipation ports, resulting in frequent shutdowns. This 220V-660V 22kw-350kw soft start cabinet, with "wide temperature tolerance + heavy load adaptability" as its core, is specially designed for metallurgical dust removal fans to ensure stable operation in high-temperature and high-dust environments. Firstly, its wide-temperature design breaks through the limitations of traditional equipment and can operate normally within the range of -25 ℃ to +60℃. Even if the temperature in the steelmaking workshop rises to + 55℃, the cabinet's intern…
