HELUCONTROL® OZ-520-HMH LS0H GREY 3x1,5 mm² grey control and power cable, black numbered cores acc. to DIN VDE 0293-334 11008687

Universal control cable for applications requiring high safety

This flexible JZ-520 HMH LS0H control cable is a reliable solution for both professional installers and end users. The cable is designed for applications in buildings with high occupancy (ZL) – office buildings, hospitals, schools, airports – where fire safety is crucial. Thanks to the halogen-free coating, it minimizes the risk of toxic gas emissions in the event of a fire, protecting health and property. This cable also performs perfectly in industrial installations, machines and air conditioning systems.

Construction and properties

The cable is characterized by a solid construction: multi-strand copper conductors provide good flexibility and connection durability. Insulation made of a halogen-free polymer mixture guarantees safe use, and a green-yellow protective conductor (from 3 conductors upwards) provides effective protection against electric shock. The strands twisted in layers with an optimal pitch minimize signal interference. The outer coating made of a halogen-free type M1 plastic (grey RAL 7001) is resistant to mechanical damage and atmospheric factors.

The JZ-520 HMH LS0H cable meets strict European standards, including CPR class B2ca-s1a, d0, a1, which confirms its high quality and safety. The cable maintains flexibility over a wide temperature range – from -15°C to +70°C (flexible) and from -40°C to +70°C (stationary). The operating voltage is 300/500 V, and the test voltage is 2000 V. The minimum bending radius ensures easy installation even in tight spaces.

Applications and benefits

• Fire safety: Halogen-free coating limits the emission of toxic gases during a fire, increasing the chances of evacuation and minimizing material losses.
• Versatility: Ideal for control installations in public buildings and in industry.
• Durability: Copper conductors and solid construction ensure long-term reliability.
• Flexibility: Allows easy installation even in difficult conditions.
• Compliance with standards: Meets the requirements of European safety standards (CPR B2ca-s1a, d0, a1).
• Resistance to external factors: Suitable for use in dry, damp and wet places and surface mounting.
• Protection against interference: Twisted strands minimize the impact of electromagnetic interference on the signal.
