Industrial distribution boxes are designed to meet IEC and EU standards, with IP65 protection, IK10 impact resistance, modular capacities, and robust busbar configurations for safe electrical distribution.

Protection and Standards

Industrial distribution boxes are typically designed to comply with IEC 62262 IK10 for impact resistance and IP65 for dust and water protection, making them suitable for harsh environments and outdoor use . They also adhere to the Low Voltage Directive 2014/35/EU, ensuring safety and regulatory compliance .

Materials and Construction

• ABS or Polycarbonate (PC) halogen-free plastics are commonly used for the base and frame, with RAL 7035 grey color for standardization .
• Transparent windows are made of UV-protected polycarbonate, suitable for outdoor exposure up to 1000 hours according to ISO 4892-2 .
• Smooth surfaces or metric-threaded options are available for cable entry .

Module Capacity and Mounting

• Distribution boxes are available in capacities of 4, 6, 8, 12, 18, 24, 36, and 54 modules .
• TH35x7.5 symmetrical rails are used for mounting modules, with one row for smaller boxes and multiple rows for larger configurations .
• Boxes are supplied pre-assembled with hinges and doors for easy installation .

Busbars and Electrical Connections

• Phase busbars are made of EC grade aluminum, with sizes depending on the box rating:
  • 63/100 KVA: 72 x 50 x 8 mm
  • 160/315 KVA: 120 x 50 x 15 mm
• Incoming and feeder droppers match busbar cross-sections: 50 x 8 mm for 63/100 KVA and 50 x 15 mm for 160/315 KVA .
• Busbars and droppers are drilled and insulated with PVC sleeves in standard color codes for phase identification .

Dimensions and Cable Management

• Standard enclosures range from 65 x 65 mm up to 361 x 254 mm, with multiple cover heights available .
• Cable lengths are standardized at 1, 2, 3, 5, or 10 meters, with provisions for PNP/NPN status indicators .
• Corners and top slopes are designed for water runoff and safety, with proper clearance for internal components .

Additional Features

• Boxes are supplied in individual packaging or bundled with transparent film for multiple units .
• Designed for chemical resistance and glow wire testing, ensuring durability in industrial environments .
• Doors are hinged on both sides for accessibility, with right door resting on the left when closed . These specifications ensure that industrial distribution boxes provide safe, durable, and modular solutions for electrical distribution in both indoor and outdoor industrial settings.
