Low smoke halogen-free control and power cable HELUCONTROL® JZ-520-HMH LS0H GREY 12G2,5 mm² grey, black numbered cores acc. to DIN VDE 0293-334 11008710

Halogen-free control cable – safety and flexibility in one>

This grey, flexible JZ-520 HMH LS0H cable is a reliable solution for control installations, especially where fire safety is a priority. The cable is designed for public places and buildings with a high risk to people (ZL), such as office buildings, hospitals, schools or stations. Its halogen-free construction minimizes the emission of toxic gases in the event of a fire, protecting health and property.

Construction and properties

The cable is characterized by a solid construction ensuring long-lasting and trouble-free operation. Made of multi-wire copper conductors, insulated with a halogen-free polymer mixture, it guarantees high flexibility and resistance to mechanical damage. The conductors are twisted in layers, which optimizes their arrangement and minimizes the risk of interference. Additionally, the cable has a green-yellow protective conductor (from 3 conductors upwards), providing additional safety. The outer jacket made of a halogen-free type M1 material provides resistance to external factors and increases the overall durability of the cable.

• Halogen-free: a key feature for safety in public buildings – minimizes the emission of toxic gases during a fire.

• Flexibility: facilitates installation and cable routing in tight spaces and with complex routes.
• Wide operating temperature range: from -40°C to +70°C (flexibly from -15°C to +70°C) – ensures reliable operation in various environmental conditions.
• CPR class B2ca-s1a, d0, a1: high fire reaction class confirmed by a certificate – a guarantee of safety in accordance with European standards EN 50575.
• Operating voltage 300/500V: versatility of use in various electrical installations.
• Oil resistance: enables use of the cable in industrial environments.

Application and compliance with standards

The JZ-520 HMH LS0H cable is perfect as a control cable in building installations and industrial machines and equipment. It is ideal for applications requiring a high level of fire safety, such as:

• Installations in public buildings (office buildings, hospitals, schools).

• Air conditioning and ventilation systems.
• Metallurgical industry.
• Production machines and equipment.
• Conveyor belts.

The cable 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 and also has a CE mark confirming compliance with the low-voltage directive 2014/35/EU. Additionally, it meets the requirements regarding smoke emission and corrosiveness of gases generated during combustion in accordance with DIN VDE and EN standards.
