1mm² 2491B Cable (H05Z-K) LSZH Pink Class 5 Flexible 300-500V LSZH-1-PINK-1

The LSZH-1-PINK-1 is a 1mm² 2491B LSZH cable (H05Z-K), a single core, flexible panel wiring cable rated 300/500V, supplied in pink in a 100m length.

This 1mm² 2491B LSZH cable is designed for internal wiring of appliances, switchgear, instrument panels, and metering equipment. Its low smoke zero halogen (LSZH) construction makes it the ideal choice where smoke and toxic fumes arising in a fire situation may threaten life or sensitive equipment. The flexible Class 5 copper conductor ensures easy routing and termination in confined enclosures.

Key Features

• 1mm² Class 5 Flexible Conductor: Plain annealed copper with 32/0.2mm stranding provides excellent flexibility for tight bends and complex panel layouts.
• LSZH Insulation (Type EI5): Cross-linked low smoke zero halogen insulation minimises toxic fume and smoke emission during fire, protecting personnel and equipment.
• 300/500V Voltage Rating: Rated to H05Z-K standards, suitable for a wide range of control panel and equipment wiring applications.
• Wide Temperature Range: Operates from -15°C to +90°C, making it suitable for demanding industrial environments.
• Compact 2.8mm Approx. Diameter: Small overall size with 0.6mm radial insulation thickness allows high-density wiring within panels and enclosures.
• Approximately 18 AWG Equivalent: Convenient cross-reference for international specifications and imported equipment.
• Pink Colour: Enables clear circuit identification and compliance with wiring colour-coding schemes.
• 100m Reel: Supplied in a practical 100m length, ideal for project-based purchasing.

Applications

This 2491B LSZH cable is suitable for internal wiring of control panels, switchgear, instrument panels, metering equipment, and appliances. It is particularly specified for installations in public buildings, transport infrastructure, data centres, and other environments where the reduction of smoke and toxic gas emissions during a fire is critical. The minimum bending radius is three times the overall diameter.

Frequently Asked Questions

What is the difference between 2491B H05Z-K and H07Z-K cable?

H05Z-K is rated 300/500V while H07Z-K is rated 450/750V; both share the same LSZH construction but H07Z-K is specified where higher voltage ratings are required.

What is the bending radius of this 1mm² 2491B LSZH cable?

The minimum bending radius is three times the overall diameter, which equates to approximately 8.4mm for this 2.8mm diameter cable.

Can this cable be used in high-temperature environments?

Yes, it is rated for continuous operation from -15°C to +90°C.

What does LSZH mean and why does it matter?

LSZH stands for Low Smoke Zero Halogen, meaning the insulation emits minimal smoke and no toxic halogen gases during a fire — essential in enclosed or populated spaces where fume inhalation poses a serious risk.
