LAPP ÖLFLEX® UNIPLUS 1X25 BN – 4521031U100 is a 25 sq. mm single-core electrical cable designed for reliable fixed electrical installations, control cabinets, switchgear and distribution applications. It features a bare copper conductor, PVC insulation and brown (BN) colour identification.
The exact LAPP article 4521031U100 is listed as a 25 mm² brown single-core cable supplied in 100 m ring packaging. LAPP's product-family data also identifies the conductor size and copper index for this article.
The 4521031U100 uses a single-core 25 sq. mm copper conductor with PVC insulation. The fine-wire stranded construction provides practical flexibility during installation while maintaining the electrical conductivity required for industrial wiring applications.
The brown (BN) colour provides clear visual identification and can help maintain organized wiring within control panels, switchgear and distribution systems. LAPP's article listing confirms 4521031U100 as 25 mm², brown, ring packaging.
The ÖLFLEX® UNIPLUS range is designed for electrical installations with a nominal voltage of up to 1.1 kV and a 3 kV test voltage. The 25 sq. mm conductor provides a larger cross-sectional area for applications requiring a higher-capacity single-core wiring solution.
For actual current-carrying capacity, the installation method, ambient temperature, grouping and applicable electrical standards should be considered.
ÖLFLEX® UNIPLUS cables are designed with flame-retardant characteristics. LAPP specifies flame retardance according to IS 10810-53 for the range. This helps limit flame propagation in suitable electrical installation environments.
Note: This is an ÖLFLEX® UNIPLUS FR cable, not an ÖLFLEX® UNIPLUS FRLS variant. It should therefore not be described as a low-smoke cable.
LAPP ÖLFLEX® UNIPLUS 1X25 BN combines a 25 sq. mm copper conductor, PVC insulation and flame-retardant characteristics in a practical single-core format. The brown colour identification makes this variant suitable for organized electrical wiring where individual conductor identification is important.
Its 100 m ring format also provides a convenient supply option for electrical installation projects.
LAPP ÖLFLEX® UNIPLUS 1X25 BN can be used for:
LAPP lists applications within the ÖLFLEX® UNIPLUS range including wiring of devices, switchgear cabinets and distribution boxes.
The 4521031U100 is intended for fixed installation. Proper cable routing, stripping and termination practices should be followed during installation to prevent damage to the PVC insulation or conductor.
LAPP's ÖLFLEX® UNIPLUS range specifies a minimum bending radius of 6 × outer diameter for fixed installation.
