HELUCONTROL® OZ-520-HMH LS0H GREY control and power cable 7x0.75 mm² grey, black numbered cores acc. to DIN VDE 0293-334 11008648

Flexible halogen-free control cable – safety and reliability

This grey, flexible control cable JZ-520 HMH LS0H is a solution designed for demanding installations where fire safety and human protection are crucial. The cable is characterized by high fire resistance and low emission of smoke and toxic gases during combustion, making it an ideal choice for public buildings and facilities with increased safety requirements.

Construction and properties

The cable is made of high-quality materials, ensuring long-lasting and reliable operation. Multi-strand copper conductors with a cross-section of 0.75 mm² guarantee good flexibility and easy installation. The core insulation is made of a halogen-free polymer mixture, which further increases safety in the event of a fire. The outer jacket made of halogen-free plastic provides protection against mechanical damage and environmental factors.

• Un-tinned, flexible copper conductors class 5 – provide good conductivity and flexibility.
• Halogen-free core insulation – minimizes the emission of toxic gases during combustion.
• LS0H (Low Smoke Halogen Free) jacket – reduces smoke emission in case of fire.
• Wide operating temperature range: from -40°C to +70°C (stationary) and from -15°C to +70°C (flexible) – enables use in various environmental conditions.
• Rated voltage 300/500 V – versatility for use in various electrical installations.
• Minimum bending radius: 4x cable diameter for fixed laying and 12.5x cable diameter for flexible laying – facilitates installation in tight spaces.

Applications and compliance with standards

The JZ-520 HMH LS0H cable is used as a control cable in buildings of Hazard to People (ZL) character, such as office buildings, hospitals, schools or railway stations. It will also be useful in industrial installations, machines, conveyor belts and air conditioning systems. It meets the requirements of DIN VDE and EN standards, and also has a fire reaction class of B2ca-s1a, d0, a1 according to EN 50575, which guarantees a high level of fire safety. Additionally, it meets the requirements of the Low Voltage Directive 2014/35/EU (CE marking).

This cable is characterized by a fire reaction class of B2ca-s1a, d0, a1 and a rated voltage of 300/500 V. The operating temperature range is from -40°C to +70°C for stationary operation and from -15°C to +70°C for flexible operation. The minimum bending radius is 4x cable diameter for fixed laying and 12.5x cable diameter for flexible laying.

Thanks to its properties, this cable is an investment in the safety and long-term reliability of the electrical installation.
