2491B / 6701B – H05Z-K / H07Z-K EN 50525-3-41 Cable

2491B / 6701B (referred to as H05Z-K & H07Z-K under the European harmonised cable standards) are primarily used for panel wiring in applications where Low Smoke Zero Halogen (LSZH) properties are required.

Product Information

Designed for use in the switch control, relay and instrumentation panels of power switchgear and for purposes such as internal connectors in rectifier equipment, motor starters and controllers, these single core cables can be installed in pipes or ducts, and used in the internal wiring of appliances with maximum operating temperatures of +90oC.

  • Application:LSZH panel wiring for appliances with maximum operating temperatures of 90°C, and generally in areas (such as public and government buildings) where smoke and toxic fumes may cause a threat to life and equipment. The cables produce no corrosive gases when burnt which is particularly important where electronic equipment is installed.
  • Suitability: LSZH flexible single core cable for internal installations in conduit, clipped direct, in free air, or on cable tray. 
  • Standards & Voltage Ratings:EN 50525-3-41, EN 60228, Flame Retardant according to IEC/EN 60332-1-2,
  • IEC/EN 60332-3-24 Halogen Free according to IEC/EN 61034-1/2, IEC/EN 60754-1/2
  • Construction:
    • Conductor
      • Class 5 flexible copper conductor
    • Insulation
      • LSZH (Low Smoke Zero Halogen)
  • Details: BASEC approved. CPR compliant. Available in a wide range of insulation colours including Green/Yellow.

The 2491B / 6701B’s Type EI5 thermoset LSZH insulation makes this range suitable for use in environments where smoke and toxic fumes arising in a fire may threaten life or equipment. It is therefore generally for use in public areas and government and commercial buildings.

The harmonised cable codes denote that there are different voltages applicable to different conductor cross-sectional area sizes. The H05Z-K cables have a rated voltage of 300/500V whilst the H07Z-K cables, applicable from CSA sizes 1.5mm2 and above, have a rated voltage of 450/750V.
