Klauke L-Series Tubular Cu Cable Lugs with 4 holes (185-800mm²)

Product overview

Klauke L-Series Tubular Cu Cable Lugs with 4 holes (185-800mm²) are tubular copper connectors with four mounting holes. They are ideal for transformer terminations and other heavy-duty electrical applications. These L-Series 4 Hole Cu Lugs feature a flared entry point that makes cable insertion quicker and easier, while also ensuring a neat finish with no raised diameter after crimping. Manufactured from tin-plated copper (EN13600) for enhanced corrosion resistance, Klauke 4 Hole Cu Lugs ensure reliable, low-resistance connections across a wide range of industrial environments.

Part Numbers: L185BO4825FMS, L240BO4825FMS, L300BO4825FMS, L400BO4825FMS, L500BO4825FMS, L630BO4825FMS, L800BO4825FMS.

Klauke L-Series Tubular Cu Cable Lugs with 4 holes (185-800mm²)

Designed for secure, code-compliant terminations, Klauke 4 Hole Cable Lugs are ideal for use with multi-stranded round conductors (e.g. to BS EN 60228 Class 2). They’re also for use on pre-rounded, multi-stranded sector-shaped conductors. The flat contact surfaces and internal chamfer ensure a straightforward, dependable connection, while the integrated inspection hole allows quick confirmation of full conductor insertion. With standardised 25mm and 35mm hole spacing, these Tubular Cable Lugs are well-suited for 4-hole transformer fixings in demanding industrial settings. Built for long-term performance, they provide consistent, safe results with minimal processing effort.
