6241B Single Core & Earth LSZH Cable – BS 7211:2012, 300/500 V, BASEC & CE Certified, Low Smoke Zero Halogen for Domestic & Fixed Installations
Product Overview
The 6241B Single Core with Earth LSZH Cable is a high-performance electrical wiring solution engineered with Low Smoke Zero Halogen (LSZH) materials — a critical safety feature designed to minimise toxic fume and corrosive gas emissions in the event of fire. This makes it ideal for homes, commercial buildings, and public spaces across South Africa, where fire safety and occupant protection are increasingly prioritised in both new developments and retrofits.
Manufactured to BS 7211:2012 standards and certified BASEC Approved, CE Marked, and backed by ISO 9001 quality management, this cable delivers consistent performance you can trust. Rated at 300/500 V, it is built for general-purpose fixed wiring where a dedicated earth continuity conductor is required — ensuring reliable earthing and circuit protection throughout your installation.
Key Features & Benefits
LSZH Construction: Low smoke, zero halogen insulation and sheath — significantly reduces smoke density and eliminates harmful halogen gases during fire. This improves visibility for safe evacuation and protects sensitive equipment and building infrastructure from corrosion.
Solid Copper Conductor: Provides excellent electrical conductivity, low resistance, and consistent current-carrying performance. The solid design ensures stable electrical characteristics and long-term durability in fixed installations.
Versatile Installation: Suitable for dry or damp premises. May be clipped directly to surfaces, laid on cable trays, or installed in free air where mechanical damage is not a concern. Also ideal for pulling into conduit or trunking — offering the mechanical protection needed in wall and ceiling voids.
Proven Compliance: Manufactured to BS 7211:2012 — the British Standard for LSZH insulated cables — and independently approved by BASEC. CE marked for conformity and ISO 9001 certified for consistent quality.
Reliable Performance Ratings: Operating temperature range from -15°C to 90°C, with short-circuit capability up to 250°C — suitable for typical South African climatic conditions, including indoor and sheltered outdoor fixed wiring. Minimum bending radius of 8× overall diameter ensures neat installation without compromising cable integrity.

Typical Applications
The 6241B 1.5mm² LSZH cable is widely used across residential homes, apartments, townhouse complexes, and domestic installations throughout South Africa — particularly recommended where fire safety is a priority:
General-purpose power and lighting circuits in houses and outbuildings
Wiring in walls, ceilings, and floors within conduit or trunking
Installation on cable trays or clipped to surfaces in dry and damp indoor areas
Any fixed wiring application requiring both a live conductor and an integrated earth continuity path
Commonly selected by consulting engineers, electrical contractors, and procurement specialists for housing developments and residential building projects — LSZH cables are increasingly specified in South African building designs to meet improved fire-safety goals, reduce health risks, and limit environmental impact in the event of a fire.
Why Choose the 6241B LSZH Cable?
When selecting wiring for South African projects, safety and compliance go hand in hand. The 6241B LSZH cable combines trusted BS 7211:2012 design with BASEC independent approval — giving you third-party verified quality that simplifies specification and tender requirements. The LSZH construction addresses a key concern in modern building design: keeping escape routes clear and safe during a fire.
With a solid 1.5mm² copper conductor rated for 24 A and a voltage rating of 300/500 V, this cable is perfectly sized for domestic lighting, power points, and general wiring circuits. It is durable, easy to install in conduit or trunking, and available in standard coil lengths or cut-to-length to suit your exact project needs — reducing waste and supporting efficient project planning.
Whether you are specifying for a new housing estate, a renovation in a coastal damp environment, or any fixed wiring project requiring reliable earthing and improved fire performance — the 6241B Single Core & Earth LSZH Cable offers the right balance of safety, compliance, and electrical performance.
