Product Category: Distribution Box

This product is a low‑voltage power distribution device compatible with the wide‑voltage range of AC 380 V‑480 V, at a rated frequency of 50 / 60 Hz and rated current from 6 A to 630 A. Manufactured from high‑quality cold‑rolled steel or stainless steel, the enclosure features a compact layout and well‑optimized internal wiring. It can integrate various components including circuit breakers, contactors, metering instruments and protective elements to realize power distribution, circuit control, safety protection and energy metering. With an ingress‑protection rating of IP40‑IP65, it meets indoor and outdoor power‑distribution requirements across industrial, commercial and building sectors.

① Wide‑voltage compatibility. Supporting AC 380 V‑480 V, it adapts to low‑voltage distribution systems of different domestic and international standards with outstanding compatibility.

② High‑grade ingress protection. The outdoor variant reaches IP55 rating. Equipped with silicone sealing gaskets and water‑deflecting edges, it delivers dust‑proof and water‑resistant performance for open‑air, humid and dusty operating conditions.

③ Robust construction. Fabricated by integral bending of 1.5 mm‑2.0 mm thickened steel plates, the cabinet offers high impact resistance, anti‑deformation performance and extended service life.

④ High functional integration. Multiple functions such as power distribution, control, metering, reactive‑power compensation and surge protection can be custom‑configured for multi‑purpose single‑cabinet deployment.

⑤ Easy installation and maintenance. A modular mounting base allows flexible component arrangement. Sealed knock‑out holes are reserved for cable entry and exit, providing ample space for wiring and servicing work.

‑ Power and lighting distribution for industrial workshops and manufacturing plants
‑ Indoor power distribution for high‑rise buildings and residential communities
‑ Commercial power distribution for shopping malls, hotels and office buildings
‑ Outdoor power distribution for photovoltaic power stations and energy‑storage projects
‑ Power distribution for corrosive‑environment sites such as sewage‑treatment plants and chemical plants
‑ Temporary power distribution for construction sites
‑ Power distribution for ports, wharves and coastal salt‑fog‑prone environments

Q1: What applications suit the 380 V‑480 V voltage range?
A: This voltage range works with domestic AC 380 V three‑phase systems, as well as overseas low‑voltage distribution systems of AC 400 V, AC 480 V and other specifications. It is ideal for sites with imported‑export equipment, foreign‑funded projects and oversea engineering assignments.

Q2: What ingress‑protection rating should be selected for outdoor deployment?
A: IP55 or higher is recommended for open‑air outdoor installation. It defends against water splash ingress and dust penetration to ensure long‑term stable equipment operation.

Q3: Are non‑standard dimensions available upon request?
A: Yes. Distribution boxes with non‑standard sizes and structures can be custom‑made according to on‑site installation space and component requirements to satisfy individualized application demands.
