2491B / 6701B (H05Z-K & H07Z-K) Cable

to 2491B Cable datasheet

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. 

2491B Cable Specification

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.

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.

 

2491B Voltage Rating

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.
