RS PRO H07Z-R Series Green Yellow Hook Up Wire 7 x 1.04 mm Stranded 100 m Thermoplastic Polyolefin 750V AC 185-3939

RS PRO 185-3939 H07Z-R Series Green Yellow Hook Up Wire is an industrial-grade cable specifically designed to ensure enhanced safety in electrical installations. Featuring a low smoke zero halogen (LSZH) thermoplastic polyolefin sheath, this cable produces minimal smoke and non-toxic fumes in the event of fire, making it ideal for use in office buildings, public facilities, and other spaces where fire safety is paramount.

The cable is constructed with 7 flexible strands of 1.04 mm copper, providing a 6 mm² cross-sectional area and ensuring both effective conductivity and ease of bending through conduits and trunking systems. Its stranded core design allows the wire to be installed in complex routing environments without sacrificing durability or electrical performance.

With a rated operating voltage of 750V AC and 450V DC, this cable suits a wide range of power distribution scenarios - from standard lighting and power circuits to earth-bonding or grounding applications. The 100 m reel packaging allows for efficient installation and reduces waste on site. The insulation wall thickness of 0.8 mm provides reliable protection against electrical faults, while the overall diameter of 5.4 mm makes it compatible with standard conduit and trunking hardware.

Green and yellow jacket colours distinguish the cable for use in earth and protective conductor roles, supporting compliance with wiring standards and facilitating maintenance and safety checks in commercial and industrial environments.

RS PRO H07Z-R Series cables comply with BS EN 50525-3-41:2011 Clause 4.1, demonstrating their suitability for installations where harmonised code requirements are enforced. The LSZH feature is particularly valuable in places where ventilation is limited and a fire event could have catastrophic effects due to smoke inhalation risks.

Applications include industrial wiring setups, commercial construction, laboratory and electrical engineering projects, and automotive battery-powered systems requiring stringent safety standards. This cable is also widely used in HVAC, water treatment, manufacturing, and facilities maintenance.

The reel contains 100 metres of wire, making it ideal for both large-scale and smaller installations. Its robust material selection and conformity with international standards ensure long-term dependability across demanding use cases.
