This series of low-voltage withdrawable switchgear is a modular cabinet type for standard modular factory assembly (FBA). It is a power distribution device for low-voltage power supply systems in metallurgy, petroleum, chemical industry, electric power, machinery, light industry, and other industries.





Our infrastructure is dedicated to R&D and manufacturing products in the power transmission and distribution field. We specialize in high and low voltage complete switchgear, charging piles for new energy vehicles, and sheet metal housing processing.
All operations are certified under ISO9001 Quality Management and ISO45001 Occupational Health and Safety. Products have passed "CCC" national mandatory certification and obtained inspection reports from authoritative institutions.
A1: It is used for energy conversion, distribution, and control in power systems with AC 50-60Hz and rated working voltages up to 660V, specifically for industries like metallurgy, petroleum, and electric power.
A2: The standard ratings include IP30 (solids >2.5mm) and IP40 (solids >1.0mm). IP54 protection against dust and sprays is available upon consultation with the manufacturer.
A3: We provide a 36-month warranty along with online support for installation training and maintenance.
A4: Yes, it complies with international standards such as IEC439-1 and VDE0660, as well as national standards like GB7251.1.
A5: It is designed for ambient temperatures between -5°C and 40°C. For transport and storage, it can withstand temperatures from -25°C to 55°C (up to 70°C for short periods of less than 24h).
A6: You should provide the model, wiring schemes, component specifications, transformer capacity (KVA), and preferred component brands (domestic or imported).
