Halogen-free mains cable

Halogen-free power cables (LSZH): useful for people, technology and critical infrastructure

In buildings with lots of people or sensitive electronics, every minute counts in the event of a fire: LSZH stands for "Low Smoke Zero Halogen" – materials that typically produce less smoke and less corrosive halogen gases than traditional PVC solutions.

Why halogen-free/LSZH is often the better choice in projects

Halogen-free sheathing and insulation materials are used where visibility and protection of technology play a greater role than the pure price per cable in the event of a fire.

  • Less smoke → better orientation/escape routes (typically tested in accordance with EN/IEC 61034, for example)
  • Less corrosive halogen gases → lower risk of corrosion on metal/electronics (typically tested e.g. according to IEC 60754)
  • Good choice for many people: schools, hospitals, public buildings
  • Good choice for expensive technology: data centres, server rooms, industrial IT

Flame propagation (depending on construction)

Important: "Halogen-free/LSZH" does not mean "fireproof". Even LSZH cables can release harmful gases such as CO in the event of a fire. The main advantage lies in smoke and corrosive halogen acids (depending on material/testing).

Practical tip: Pay attention to material specifications such as H05Z1Z1-F (example) and approvals (e.g. VDE/ENEC) if these are required for the project.

Go directly to suitable LSZH items

Frequently selected in everyday B2B use: Schuko (CEE 7/7) to IEC C13 and LSZH cold device extensions C13 to C14 – ideal for IT, servers and infrastructure.

Schuko → C13 (1.8 m) Schuko → C13 (3 m) Schuko → C13 (5 m) C13 → C14 extension

Note: Availability and technical details can be found for each item (e.g. cross-section, length, approval).

FAQ: Halogen-free / LSZH – brief answers

What does "halogen-free" mean in relation to cables?

"Halogen-free" refers to sheathing/insulation materials without halogen-containing components. In the event of a fire, this typically results in fewer acidic/corrosive halogen gases (test context e.g. IEC 60754).

What does "low smoke" mean in LSZH?

"Low smoke" describes reduced smoke development – measured, for example, by smoke density/light transmission in test procedures (test context, e.g. EN/IEC 61034).

Is LSZH automatically "flame-retardant"?

Not automatically. Fire behaviour depends on the overall cable structure. Different tests are used for flame propagation depending on the application (test context, e.g. IEC 60332).

What information do I need for a quick recommendation?

Plug type + coupling (e.g. Schuko→C13, C13→C14), length, cross-section/power requirement and application environment (office, server room, public, industrial).
