Halogen-free control and power cable, shielded HELUCONTROL® JZ-520-HMH-C LS0H GREY 12G2,5 mm² grey, black numbered cores acc. to DIN VDE 0293-334 11008804

Halogen-free shielded control cable – safety and reliability

This flexible control cable JZ-520 HMH-C LS0H is designed for demanding applications where fire safety and protection against electromagnetic interference are crucial. Made of high-quality materials, this cable is perfect for installations in public buildings, industry, and anywhere high reliability and resistance to harsh conditions are required.

Construction and properties

The cable features a solid construction ensuring long-lasting and trouble-free operation. It uses multi-wire copper conductors of flexibility class 5, which guarantees flexibility and resistance to mechanical fatigue. The core insulation is made of a halogen-free polymer mixture, which reduces the emission of toxic gases and smoke in the event of a fire – this is crucial for the safety of people and equipment. In addition, a screen in the form of a braid of copper wires provides effective protection against electromagnetic interference (EMC), which is important in industrial environments and in buildings with sensitive electronics. The outer sheath is made of a halogen-free plastic, which further enhances the level of safety.

• Halogen-free: Reduces the risk of toxic gas formation during a fire, protecting health and life.
• Shielding: Copper braid minimizes the impact of electromagnetic interference on control signals.
• Flexibility: Class 5 stranded conductors make it easy to install and lay the cable, even in tight spaces.
• Weather resistance: The cable is suitable for use in both dry and wet locations.
• CPR class B2ca: Meets stringent European standards for reaction to fire – s1a (low smoke density), d0 (no burning droplets), a1 (no flame contribution).

Applications and compliance with standards

The JZ-520 HMH-C LS0H cable is widely used as a control cable in public buildings (office buildings, hospitals, schools), industrial facilities, and anywhere high fire safety is required. It is ideal for air conditioning installations, building automation systems, and production machines and equipment. Thanks to its shielding, it is also suitable for transmitting measurement and control signals in environments exposed to electromagnetic interference.

Meets the requirements of standards: DIN VDE 0285-525-3-11/DIN EN 50525-3-11 and DIN VDE 0285-525-2-51/DIN EN 50525-2-51. It has a CE certificate confirming compliance with the Low Voltage Directive 2014/35/EU. To optimize electromagnetic compatibility, it is recommended to ensure bilateral contact of the copper braid with the terminals (e.g. EMC cable glands).
