6243B 3-Core & Earth LSZH Cable – BS 7211:2012, 300/500V, Low Smoke Zero Halogen Fire-Safe Wiring Cable

Overview

The 6243B 3-Core & Earth LSZH Cable is a premium Low Smoke Zero Halogen (LSZH) fixed wiring cable, engineered to meet the highest safety and performance standards for electrical installations across South Africa and beyond. Designed explicitly for environments where fire safety, smoke control, and toxic fume suppression are critical priorities, this cable delivers reliable power and lighting wiring while minimising life-safety risks in the event of a fire. It is fully certified to international benchmarks and manufactured in accordance with BS 7211:2012, making it a trusted choice for engineers, specifiers, and technical procurement professionals working on commercial, public, and high-occupancy projects.

In South Africa’s built environment—where large public buildings, shopping centres, schools, hospitals, hotels, and multi-unit residential complexes demand robust fire-performance materials—LSZH cables such as the 6243B range are increasingly specified. Unlike conventional PVC-sheathed cables, LSZH constructions emit almost no toxic halogen gases and produce very low levels of dense smoke when exposed to fire. This is vital: in an emergency, clear visibility and the absence of corrosive fumes enable safer evacuation, reduce harm to occupants and first responders, and limit long-term damage to sensitive electrical and electronic equipment—making it the responsible specification for any space where people gather.

Key Features & Benefits

• Low Smoke Zero Halogen (LSZH) Construction: Produces minimal smoke and no toxic or corrosive halogen emissions under fire conditions—critical for escape routes, air-conditioned spaces, and densely occupied buildings.

• Solid Copper Conductors: High-purity solid copper ensures excellent conductivity, low electrical resistance, and consistent long-term performance.

• 300/500 V Voltage Rating: Suitable for standard low-voltage interior wiring, including lighting circuits and general socket outlets.

• Broad Operating Temperature Range: Performs reliably from -15°C up to 90°C, withstanding the heat generated in normal operation and elevated ambient temperatures common in many South African installations.

• Short-Circuit Rating: Withstands conductor temperatures up to 250°C during short-circuit events, providing circuit integrity and fire resistance under fault conditions.

• Minimum Bending Radius: Can be bent to a minimum radius of 8× overall cable diameter, balancing ease of installation with mechanical performance.

• Fully Certified Quality: BASEC Approved, CE Marked, and manufactured under ISO 9001 quality management systems—verifying consistent manufacture, compliance, and traceability.

• Compliant Design: Manufactured to BS 7211:2012, the recognised British Standard for LSZH domestic and fixed wiring cables, widely accepted and specified across South Africa and international markets.

Construction & Technical Specifications

Product Range & Technical Data

The 6243B series is available in three common conductor sizes to suit lighting and general-purpose circuit requirements:

Installation & Application

The 6243B LSZH cable is intended for fixed interior installations in dry or damp indoor environments, where fire safety and low-smoke performance form part of the design specification. It may be installed:

• Clipped directly to surfaces or building fabric.

• Supported on cable trays or in free air, where mechanical protection is adequate.

• Pulled into conduit, trunking, or ducting where additional mechanical protection is required.

It is not intended for direct burial, outdoor use without protection, or high-mechanical-stress applications such as heavy industrial floor areas—unless additional mechanical protection is provided.

Ideal Use Cases

• Lighting and socket outlet wiring in domestic, commercial, and institutional buildings.

• Public-access and high-occupancy buildings: schools, hospitals, offices, hotels, shopping centres, and apartment blocks.

• Areas with enhanced fire-safety requirements: escape routes, stairwells, plant rooms, basements, and enclosed car parks.

• Projects specifying LSZH materials: new developments, renovations, and public-sector infrastructure where halogen-free, low-smoke cabling is required by design codes or insurance requirements.

In South Africa, where the National Building Regulations (SANS 10400) and wiring code (SANS 164-1) increasingly align with international fire-safety best practice, the 6243B range offers a dependable solution that satisfies both performance and compliance requirements. Whether you are designing a new commercial development in Cape Town, upgrading a public facility in Gauteng, or specifying cabling across KwaZulu-Natal, the 6243B provides the peace of mind that comes with BASEC certification and proven LSZH performance.

Quality & Compliance

Every length of 6243B cable is manufactured to BS 7211:2012, audited and approved by BASEC, and carries the CE marking for conformity with European standards. Production operates under an ISO 9001 quality management system, ensuring consistency from batch to batch. This means you can specify with confidence: the 6243B meets recognised international standards, is independently verified, and is backed by rigorous quality control—essential for tender compliance, project acceptance, and long-term safety.

Ordering & Availability

Stocked in standard 50 m and 100 m coils, with cut-to-length services available to meet exact project requirements. Sizes from 1.0 mm² through 2.5 mm² cover the full spectrum of interior lighting and general-circuit wiring needs.

Why Choose the 6243B Series?

When safety is non-negotiable, the 6243B 3-Core & Earth LSZH cable delivers on every front: low-smoke zero-halogen fire performance, trusted international standards, independent certification, and a size range tailored to interior lighting and fixed wiring. It is the smart specification for engineers, quantity surveyors, and procurement professionals who must balance performance, compliance, and value—while protecting lives, property, and business continuity.
