SDS Power Distribution Cabinet & Box

SDS up to 630 A + SDSF up to 400 A — modular LV distribution cabinets and boxes for industrial and civil buildings.

What is SDS Power Distribution Cabinet & Box?

The SDS series power distribution cabinet is built for power plants, substations, petroleum, chemical, metallurgical, mechanical and high-rise building LV systems — handling power, distribution, motor and control-center loads. The companion SDSF distribution box operates at 50–60 Hz, rated working voltage ≤ 500 V and rated working current up to 400 A, used as protection for lighting and motor-control circuits in industrial, civil, mining, high-rise, station, hospital and residential buildings.

Where SDS / SDSF fits

• All types of industrial facilities

• Civil & residential buildings

• High-rise buildings, stations, hospitals

Operating conditions

• Short-term maximum ambient: 40 °C

• Minimum long-term average ambient: −5 °C

• Maximum long-term average ambient: 35 °C

• Standard operating relative humidity: 50 %

Derating required when ambient temperature exceeds the limits above. For measurement, metering and protection-relay operating conditions, follow the manufacturer's instructions.

SDS / SDSF at a glance

• SDS max rated current: 630 A

• SDSF max rated current: 400 A

• SDSF rated voltage / frequency: ≤ 500 V, 50–60 Hz

• Cabinet frame: 8MF cold-formed steel with 20-mod mounting holes

• Protection: IP30 standard, configurable IP20–IP40

SDS / SDSF key features

• Universal cabinet frame in 8 MF cold-formed steel with modular 20-mod mounting holes for high cross-platform usability.

• Optimized thermal design with dedicated upper exhaust vents and lower intake vents creating natural convection through the sealed cabinet.

• Modern industrial styling based on the golden-ratio proportion principle.

• Removable top cover simplifies on-site busbar installation and adjustment; lifting rings on all four corners.

• Standard IP 30 protection; configurable to IP 20 – IP 40.

• Optional digital experience layer for software-assisted collaboration.

Business Values for Operators

• One cabinet family, multiple use cases — SDS for power/distribution/motor/control-center loads (up to 630 A) plus SDSF for lighting and motor-control protection (up to 400 A), unified procurement under one platform.

• Universal 8MF frame — high cross-platform usability simplifies spare-parts, retrofit decisions and engineer training across multiple site types.

• Natural-convection thermal design — dedicated upper exhaust / lower intake vents keep the cabinet sealed and cool, lowering fan-maintenance cost.

• IP30 standard, configurable to IP20–IP40 — match protection grade to specific dust, humidity and contamination levels on site.

• Site-friendly installation — removable top cover and four-corner lifting rings make on-site busbar assembly and hoisting straightforward.

• Golden-ratio industrial design — clean modern appearance suitable for visible plant-room installations.

Frequently Asked Questions

• What is the difference between SDS and SDSF?
  SDS is the larger power-distribution cabinet (up to 630 A) used for power, distribution, motor and control-center loads. SDSF is the smaller distribution box (up to 400 A, ≤ 500 V) used for lighting and motor-control circuit protection.

• Can SDS / SDSF serve both industrial and civil projects?
  Yes — both families are designed for industrial facilities, civil buildings, high-rise buildings, stations, hospitals and residential projects.

• Can the protection grade be raised for harsh environments?
  Yes — IP30 standard, field-configurable to IP20–IP40 to match dust, humidity and contamination levels.
