Cable junction boxes with intrinsic fire resistance and insulation integrity

Product catalog summary
Overview: The document provides comprehensive information on Hensel's cable junction boxes, which are designed to ensure reliable power supply during fires. These boxes are engineered to maintain fire resistance and insulation integrity, crucial for the functionality of emergency power systems in critical situations.
Specifications:
  • Fire Resistance: Junction boxes are tested for fire resistance according to DIN 4102 Part 12, with classifications E30, E60, and E90, indicating their functional duration during a fire.
  • Insulation Integrity: Achieves PH120 classification under BS EN 50200, ensuring insulation integrity for up to 120 minutes during fire exposure.
  • Material and Design: Constructed from thermoplastic or sheet steel, these boxes emit no toxic or corrosive substances and are available in orange (RAL 2003).
  • Protection and Durability: Rated IP65/IP66 for dust and water protection, with a glow wire test rating of 960°C and impact resistance of IK09.
Procedures:
  • Planning and Compliance: Installation must adhere to country-specific regulations and standards, including local fire safety laws.
  • Selection Criteria: Consider fire resistance requirements, installation procedures, and building materials when selecting materials and manufacturers.
  • Installation: Professional installation is essential to ensure system reliability during a fire.
Testing and Standards:
  • Intrinsic Fire Resistance: Tested as a complete system, including cables and support structures, under real-life conditions to ensure functional integrity.
  • Insulation Integrity: Focuses on the cable's ability to maintain insulation without mechanical load during fire exposure.
Applications: These junction boxes are ideal for buildings with high public traffic, such as department stores, airports, and hospitals, where maintaining emergency power supply during a fire is critical.
Materials and Construction: The junction boxes are made from polycarbonate and sheet steel, with powder-coated finishes for durability. They are suitable for normal and protected outdoor environments, with rated insulation voltages of 400 V a.c./d.c. and current carrying capacities ranging from 32 A to 150 A.
Installation and Usage: Mounted using exterior wall fixings, suitable for various building materials like concrete, limestone blocks, and bricks. Features include screw anchors, ceramic connecting terminals, and mounted grommets for cable entry.
Fire Resistance and Testing: Approved for intrinsic fire resistance according to DIN 4102 Part 12, tested with multiple cable manufacturers. Approval from building and regulatory authorities is crucial for specific applications, especially in emergency lighting and telecommunications installations.
Technical Details: Provides information on box fixing with anchors, specifying compatible anchor types for different building materials, ambient temperature range, and glow wire test standards.
Environmental Conditions: Specifies ambient temperature ranges with average, maximum, and minimum values: +35°C, +40°C, and -25°C respectively. Details relative humidity conditions for short-term exposure: 50% at 40°C and 100% at 25°C.
Materials and Protection: Uses polycarbonate and powder-coated sheet steel, both halogen-free. Specifies protection against mechanical load as IK09 (10 Joule) and IK10 (20 Joule).
Standards and Regulations: References several standards, including IEC 60998-1, IEC 60998-2-1, IEC 60670-22, IEC 60529, EN 60947-7-1, DIN EN 50262, DIN 4102 Part 12, and EN 50200, covering requirements for connecting devices, protection degrees, fire resistance, and cable glands.
Company Information: Issued by Gustav HENSEL GmbH & Co. KG, a company specializing in industrial electrical power distribution systems, based in Germany. Contact information includes phone, fax, email, and website details.

Cable junction boxes with connected cables after testing DIN 4102-12 Intrinsic fire resistance for 30 minutes Intrinsic fire resistance E30/E60/E90 places higher demands In contrast to insulation integrity, the testing of intrinsic fire resistance accesses not just a single test product, but the cable system as a whole including all components. The German standard DIN 4102-12 sets the requirements on a complete cable system to achieve the functional integrity in the event of fire. Testing of functional integrity sets extreme but realistic demands on a complete cable system in combination with all...
