① High IP55 ingress‑protection rating. Purpose‑built for outdoor waterproof and dust‑proof performance, the unit can be installed outdoors directly without additional protective shelters and copes with a wide range of harsh outdoor environments.

② 400 A high‑current capacity. It meets power‑supply demands of high‑load outdoor equipment, construction sites, base stations and other heavy‑duty applications.

③ Weather‑resistant cabinet materials. UV‑resistant and anti‑corrosive, the enclosure delivers long service life and adapts to outdoor climatic conditions including extreme temperatures, rain and snow.

④ Comprehensive protection suite. Real‑time monitoring of electrical parameters triggers automatic power cut‑off upon abnormalities to guarantee outdoor electricity‑use safety.

⑤ Modular design. Internal components can be flexibly configured to satisfy power‑distribution requirements of diverse outdoor scenarios.

‑ Temporary power supply for outdoor construction sites
‑ Outdoor power distribution for communication base stations
‑ Outdoor bus power distribution for photovoltaic power stations
‑ Power distribution for municipal road lighting
‑ Power supply for outdoor amusement facilities
‑ Power distribution for field‑exploration operations
‑ Outdoor irrigation power supply in rural areas
‑ Power distribution for outdoor equipment in scenic spots

Q1: What does IP55 mean for an outdoor distribution cabinet?

A: IP55 means the cabinet is fully dust‑tight and protected against low‑pressure water jets. It resists rain spray and dust intrusion and is qualified for direct outdoor installation.

Q2: What is the maximum power load for a 400 A distribution cabinet?
A: Under AC 380 V three‑phase operating conditions, the 400 A rated current corresponds to approximately 200 kW. It satisfies high‑load requirements for large outdoor equipment and temporary power consumption at construction sites.

Q3: Are extra waterproof measures required?
A: The cabinet itself carries IP55 waterproof rating. No extra waterproof treatment is needed for standard outdoor installation. Only proper foundation fixing is required to prevent the cabinet base from being submerged by accumulated water.
