Single-core halogen-free cable H07Z-K 1x4 mm² dark blue, cardboard roll 52955

Halogen-free cables – safety and fire protection

This single-core H07Z-K cable with a cross-section of 4 mm² in dark blue, supplied in a practical cardboard box, is a reliable solution for installations requiring increased fire resistance. Made of a flexible class 5 copper core, covered with halogen-free insulation, it minimizes the emission of toxic gases and smoke in the event of a fire – which is crucial for the safety of people and installations. Complies with DIN VDE 0285-525-3-41 / DIN EN 50525-3-41 standards, guaranteeing a high level of protection.

Application and properties

This cable is used wherever fire safety is a priority. It is ideal for electrical installations in public buildings, industrial facilities, and in the wiring of devices and switchboards. It can be used both on and under plaster, as well as in closed cable ducts. Thanks to its flexible construction, it is easy to install and route. The cable is designed to operate at voltages up to 750V DC or 1000V AC relative to earth.

Construction and technical parameters

The H07Z-K cable is characterized by a solid construction ensuring long-lasting and reliable operation. The stranded copper core meets the requirements of DIN VDE 0295 cl. 5, BS 6360 cl. 5 and IEC 60228 cl. 5. The insulation is made of cross-linked halogen-free mixture type EI5 according to DIN VDE 0207-363-5 / DIN EN 50363-5. The approximate outer diameter of the cable is 4.35 mm, and its conductor resistance complies with DIN VDE 0295 cl. 5. The cable has a fire reaction class of Eca (CPR). The operating temperature range is from -40°C to +90°C, allowing it to be used in various environmental conditions. The rated voltage U/U0 is 750/450V respectively.
