Halogen-free control and power cable, shielded HELUCONTROL® JZ-520-HMH-C LS0H GREY 25G1 mm² grey, black numbered cores acc. to DIN VDE 0293-334 11008789

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, especially in public buildings. The cable construction, using halogen-free materials, minimizes the emission of toxic gases in the event of a fire, protecting the health and lives of users and sensitive electronics. Shielding ensures stable signal transmission, eliminating electromagnetic interference.

Construction and properties

The cable is characterized by a solid construction, designed for long-term and reliable operation. It is made of multi-strand copper conductors of flexibility class 5, which ensures high flexibility and resistance to mechanical fatigue. The conductor insulation is made of halogen-free TI7 polymer mixture, guaranteeing safety in case of fire. Protective conductors (in versions with a protective conductor) are placed in the outer layer of the core for increased safety. The copper wire shielding braid with a coverage density of approx. 85% effectively suppresses electromagnetic interference, ensuring stable signal transmission. The outer jacket is made of halogen-free M1 plastic, which further increases the level of fire safety.

Key features of the cable include:

• Halogen-free: Reduces the risk of poisoning by toxic gases during a fire.
• Shielding: Provides resistance to electromagnetic interference (EMC).
• Flexibility: Facilitates installation and routing of the cable in tight spaces.
• Durability: Made of high-quality materials resistant to mechanical damage and weathering.
• CPR class B2ca: Meets stringent European standards regarding reaction to fire.

Applications and compliance with standards

The JZ-520 HMH-C LS0H cable is primarily used in buildings of the People Hazard (ZL) character, such as office buildings, hospitals, schools, airports or railway stations. It is ideal for control, measurement installations and in industrial machines and equipment. It can be used in both fixed and flexible installations, in dry and humid environments. Thanks to its high resistance to EMC interference, it performs perfectly in applications requiring precise signal transmission.

It meets 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
• EN 50575 (class B2ca-s1a, d0, a1)
• DIN VDE 0482-399 / DIN EN 50399 (flame retardancy of cable bundles)
• DIN VDE 0482-332-1-2 / DIN EN 60332-1-2 / IEC 60332-1-2 (flame retardancy of single core)
• 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 to connect the shielding braid to the terminals on both sides for optimal protection against EMC interference!
