Halogen-free control and power cable, shielded HELUCONTROL® JZ-520-HMH-C LS0H GREY 3G1,5 mm² grey, black numbered cores acc. to DIN VDE 0293-334 11008791

Halogen-free shielded control cable – safety and reliability

This flexible JZ-520 HMH-C LS0H control cable is a solution dedicated to installations requiring a high level of fire safety and protection against electromagnetic interference. The cable is designed for public buildings, industrial facilities and anywhere where minimizing risk in the event of a fire is key. Its construction, based on halogen-free materials, limits the emission of toxic gases and smoke during combustion, protecting people's health and sensitive electronics.

### Construction and properties

The cable is characterized by a solid construction ensuring long-lasting and reliable operation. It is made of multi-strand copper conductors, which guarantees flexibility and resistance to material fatigue. The core insulation made of halogen-free TI7 polymer mixture provides high dielectric properties and temperature resistance. Protective conductors (green-yellow) are located in the outer layer of the core for increased safety. A braid of tinned copper wires with a coverage density of approximately 85% effectively shields the cable against electromagnetic interference (EMC), ensuring stable signal transmission. The outer sheath made of halogen-free type M1 plastic further increases the level of fire safety.

* Halogen-free: Reduces the emission of toxic gases during a fire, protecting health and life.

• Shielding: Copper braid minimizes electromagnetic interference, ensuring stable signal transmission.

• Flexibility: Multi-strand copper conductors make it easy to install and lay the cable in tight spaces.

• Temperature resistance: The cable retains its properties over a wide temperature range – from -40°C to +70°C (flexibly from -15°C to +70°C).

• CPR class: B2ca-s1a, d0, a1 – high reaction to fire class according to EN 50575.

• Operating voltage: 300/500 V – universal application in electrical installations.

### Applications and compliance with standards

The JZ-520 HMH-C LS0H cable is used as a control cable in buildings of the People Hazard (ZL) character, such as office buildings, hospitals, schools or airports, where the highest standards of fire safety are required. It will also be useful in industrial installations, machines, conveyor belts and air conditioning systems. Thanks to the shielding, it is ideal for transmitting signals in environments exposed to electromagnetic interference.

The cable meets the requirements of the following standards:

* DIN VDE 0285-525-3-11 / DIN EN 50525-3-11

• DIN VDE 0285-525-2-51 / DIN EN 50525-2-51

• DIN VDE 0482-399 / DIN EN 50399 (flame retardancy of cable harness)

• DIN VDE 0482-332-1-2 / DIN EN 60332-1-2 / IEC 60332-1-2 (flame retardancy of single cable)

• DIN VDE 0482-754-2 / DIN EN 60754-2 / IEC 60754-2 (corrosivity of gases)

• DIN VDE 0482-1034-1+2 / DIN EN 61034-1+2 / IEC 61034-1+2 (smoke emission)

• DIN VDE 0482-754-1 / DIN EN 60754-1 / IEC 60754-1 (halogen-free)

• DIN VDE 0473-811-404 / DIN EN 60811-404 / IEC 60811-404 (oil resistance)

Remember about the bilateral, circumferential contact of the copper braid with the terminals (e.g. EMC cable glands) for optimal electromagnetic compatibility. The product is compliant with the Low Voltage Directive 2014/35/EU (CE marking).
