Applications Overview

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

Conductor Flexible copper (Class 5)
Insulation Low Smoke Zero Halogen (LSZH) Type EI5

The 2491B / 6701B's LSZH Type EI5 thermosetting 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.
