Stainless Steel AC Distribution Cabinet

Material: stainless steel
Color: Gray
Place of Origin: Shanxi, China
Application: Industrial
Product Category: Distribution Box

This product is a low‑voltage AC power distribution device with cabinets primarily constructed from SUS304 / SUS316 stainless steel. Compatible with AC 220 V / 380 V low‑voltage distribution systems, it supports rated currents ranging from 6 A to 6300 A. The cabinets are manufactured through laser cutting, bending, welding, and surface brushing or sandblasting treatments, delivering outstanding corrosion resistance, salt‑fog tolerance, rust‑proof performance and easy‑to‑clean properties. Internally, it can accommodate components such as circuit breakers, contactors, PLC units and metering instruments to realize power distribution, circuit control, protection and energy metering functions. With an ingress‑protection rating of IP54‑IP65, it is well‑suited for harsh industrial environments including humid, acid‑alkaline, dusty and coastal conditions.

① Superior corrosion resistance. SUS304 stainless steel contains chromium and nickel elements and offers good tolerance to atmospheric exposure, fresh water and weak acid‑alkaline media. SUS316 stainless steel incorporates additional molybdenum, which greatly improves resistance to chloride‑ion and salt‑fog corrosion. Ideal for highly corrosive settings such as coastal and chemical‑industry sites, it achieves an outdoor service life of more than 15 years.

② High structural strength. One‑piece formed cabinets made of 1.5 mm‑2.0 mm thickened stainless‑steel plates feature high impact resistance and anti‑deformation performance. Surface scratches will not develop into corrosion spots, resulting in extremely low maintenance costs.

③ High‑grade ingress‑protection performance. Equipped with polyurethane foam sealing gaskets and water‑deflecting edges, the cabinet reaches IP65 rating for complete dust‑proof and water‑jet‑proof performance, suitable for open‑air outdoor locations and wash‑down applications.

④ Easy cleaning and maintenance. The smooth stainless‑steel surface resists dust accumulation and permits direct water rinsing, making it ideal for hygiene‑critical sites such as food‑processing and pharmaceutical clean‑rooms.

⑤ Attractive and durable finish. Brushed or sandblasted surface treatment delivers premium texture and anti‑discoloration properties, satisfying aesthetic requirements for commercial buildings and public‑facility installations.

Q1: What are the differences between SUS304 and SUS316 stainless‑steel distribution cabinets?
A: SUS304 is a general‑purpose grade with high cost‑efficiency for atmospheric, fresh‑water and mild acid‑alkaline environments. SUS316 contains molybdenum and provides stronger resistance to chloride ions, salt fog and strong acids. It is preferred for highly corrosive conditions such as coastal zones, chemical‑processing plants and offshore‑engineering projects.

Q2: What is the maximum achievable ingress‑protection rating for stainless‑steel distribution cabinets?
A: With fully‑sealed construction and dedicated sealing gaskets, the maximum ingress‑protection rating reaches IP65, which safeguards stable long‑term operation under open‑air rain exposure and dusty conditions.

Q3: How much more expensive are stainless‑steel distribution cabinets compared with ordinary cold‑rolled‑steel cabinets?
A: Stainless‑steel cabinets of equivalent specifications generally cost 30 %‑50 % more than powder‑coated cold‑rolled‑steel cabinets. Nevertheless, they feature longer service life and lower maintenance expenses for improved whole‑life‑cycle economics.
