LSZH 2491B / 6701B

2491B / 6701B (H05Z-K & H07Z-K) is a flexible, single-core Low Smoke Zero Halogen (LSZH) panel wire designed for switchgear, control panels and the internal wiring of electrical equipment and appliances. Flame retardant and free from halogens, it produces minimal smoke and no toxic, corrosive fumes when exposed to fire, making it the wire of choice for installations where the safety of people and equipment is a priority. This makes it especially well suited to public, government and commercial buildings such as hospitals and schools.

Manufactured to BS EN 50525-3-41 (formerly BS7211) and BASEC approved, the range features a Class 5 flexible copper conductor with LSZH insulation, rated to a maximum operating temperature of 90°C. Also known as LSOH or LSHF cable, it is available in a wide choice of insulation colours, with H05Z-K sizes (0.5mm² to 1.0mm²) rated at 300/500V and H07Z-K sizes (1.5mm² and above) rated at 450/750V
