Internal Structure: This wall-mounted surface distribution cabinet features neat internal layout and standardized wiring. It is equipped with core electrical components including 3-phase main circuit breakers, branch MCBs, residual current protection devices, and dedicated neutral/ground copper bars. All circuits are independently partitioned to provide reliable protection against overload, short circuit and electric leakage. Sufficient reserved expansion space allows optional installation of surge protectors, ATS automatic transfer modules and other accessories. Clear phase color marking and standard wiring greatly simplify later maintenance and troubleshooting.
Selling Points: The cabinet body is made of thick cold-rolled steel plate with electrostatic powder spraying finish, delivering excellent moisture-proof, dust-proof, anti-corrosion and rust-resistant performance to adapt to humid and harsh working environments. Equipped with sealing rubber strips and lockable safety door, it effectively prevents unauthorized access and misoperation for maximum safety. The wall-mounted surface installation design requires no wall embedding, ensuring quick and on-site easy installation and high construction efficiency. With outstanding power supply stability and long service life, it supports customized ATS emergency switching function to guarantee uninterrupted power supply, perfectly meeting strict power demands of high-reliability buildings.
Customized for the Guinea-Bissau Airport project, this product is perfectly applied to airport control towers and airport technical buildings. It is also widely suitable for industrial plants, commercial buildings, municipal projects, rail transit infrastructure and other scenarios. It can serve as conventional power and lighting distribution equipment, and can also be upgraded to ATS uninterrupted emergency power distribution cabinet, providing continuous and stable power guarantee for critical primary loads.
