Cable lug, crimp terminal with insulation, insulation color: blue, cross-section 2.5mm2, length 12mm DUI-2,5-12NB

Cable lugs – reliable electrical connections

Crimped terminals with insulation are an essential element in any electrical installation. They are used to safely and permanently terminate wires, preventing fraying and ensuring optimal conductor cross-section. Made of tinned copper and insulated with polypropylene, they guarantee high-quality connections and protection against corrosion.

Construction and application

These cable lugs, with a cross-section of 2.5 mm² and a sleeve length of 12 mm, are designed for stranded wires. Their use minimizes the risk of short circuits and allows for full utilization of the conductor cross-section, which translates to efficient operation of the installation. Tinning provides additional protection against corrosion and improves electrical conductivity. The total length of the terminal is 18 mm.

Key features and benefits

• Tinned copper: provides excellent conductivity and corrosion resistance – the connection is stable and durable for a long time.
• Polypropylene (PP) insulation: ensures safe use and protects against accidental short circuits. The blue color facilitates identification of the wire cross-section.
• Complies with DIN 46228-4 standard: guarantees quality and compatibility with other elements of the electrical installation.
• Optimal cross-section: 2.5 mm² is a popular size used in many domestic and industrial installations.
• Sleeve length 12 mm: ensures a solid mechanical connection with the wire.
• Operating temperature up to +105°C: allows use in various environmental conditions.

Dimension d1 (hole diameter) is 2.2 mm, d2 (insulation diameter) is 4.2 mm, l1 (total length) is 18 mm, and l2 (sleeve length) is 12 mm. The sleeve wall thickness (s1) is 0.15 mm, and the insulation thickness (s2) is 0.25 mm.

These terminals are ideal for both professional installers and end-users who perform electrical work themselves. They provide safe, durable and reliable connections in any installation.
