Pushing high-power systems to their limits often exposes weaknesses in connections that can’t handle the load or stress over time. Our Four-Hole Copper Lugs, made from high-conductivity copper, bring rugged strength and superior power control to keep your setups thriving under pressure.

Material Composition

High-conductivity electrolytic copper

Conductor Size Range

10 mm² to 500 mm² (AWG 8 to 1000 MCM), customizable upon request

Current Carrying Capacity

100 A to 1500 A, depending on conductor size and ambient conditions

Dimensions

Length: 60 mm to 180 mm; Barrel diameter: 10 mm to 35 mm; Stud holes: 8 mm to 20 mm (customizable)

Weight

40 g to 450 g, depending on size and barrel length

Product Description

Flimsy lugs or shaky fits can lead to failures that halt production or damage your reputation. Our four-hole lugs stand firm with a tensile strength of 1000 N to 5000 N, offering lasting performance for applications that demand both power and resilience.

Barrel Length

20 mm to 50 mm, ensuring secure crimping and conductor retention

Termination Type

Four-hole stud design; stud sizes from 8 mm (M8) to 20 mm (M20) for maximum mounting stability

Crimping Compatibility

Compatible with hexagonal, indent, or circular crimping tools; hydraulic tools recommended

Operating Temperature Range

-55°C to 150°C, maintaining conductivity under thermal stress

Surface Finish

Bare copper or tin-plated options, enhancing corrosion resistance and contact efficiency

Voltage Rating

Up to 35 kV, suitable for low to medium voltage applications (insulation-dependent)

Tensile Strength

1000 N to 5000 N, ensuring exceptional mechanical stability with quad-hole anchoring

Environmental Resistance

IP54 rating; resists oxidation and moisture in controlled indoor/outdoor environments

Standards Compliance

Conforms to IEC 61238-1, EN 61238-1, UL 486A-486B, and RoHS for safety and performance

Installation Method

Crimp-on only; designed for heavy-duty crimping tools

Conductor Compatibility

Supports stranded or solid copper conductors (Class B to Class K), ideal for large wires

Technical Advantages

Our four-hole copper lugs tackle currents from 100 A to 1500 A, delivering robust power delivery for demanding systems. Operating from -55°C to 150°C, they maintain stability across intense thermal shifts, cutting the risk of joint failure.

Bare copper or tin-plated surface finishes resist moisture (IP54 rating) and oxidation. That toughness ensures your setups hold up, reducing repair needs in high-stress environments.

Built for Lasting Power

Your applications need connections that match their strength and longevity. Our four-hole lugs, weighing 40 g to 450 g, use a four-hole stud design (8 mm to 20 mm) and crimp-on installation to anchor securely in your designs.

Power instability shouldn’t cut short your system’s life. With conductor sizes from 10 mm² to 500 mm² and voltages up to 35 kV, our lugs keep your setups powered and compliant with IEC 61238-1, EN 61238-1, and UL 486A-486B standards.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

What if mismatched lug designs cause connection failures in my mixed-power setups?

Our four-hole copper lugs adapt to a wide range of conductor sizes, ensuring a strong fit across diverse power needs in your systems. Their four-hole stud design distributes stress evenly, reducing the chance of failure where single- or two-hole options might not align. This flexibility saves you from costly redesigns or mismatched replacements down the line.

How do our lugs handle thermal expansion that loosens joints in high-heat operations?

Built from high-conductivity copper, our lugs pflegen a firm grip through wide temperature swings, countering expansion that could weaken connections. The extended barrel length enhances crimping strength, keeping joints stable even under heat stress. As a result, you avoid unexpected downtime or safety risks from shifting contacts.

What stops installation mistakes from driving up my labor costs in large projects?

Our lugs work with standard crimping tools—manual or hydraulic—making setup straightforward and consistent across your team. The four-hole layout offers clear mounting points, cutting the odds of errors during assembly. This ease keeps your labor expenses in check, even on big installations.

How can I avoid frequent lug replacements eating into my maintenance budget?

Our four-hole copper lugs feature a robust build with surface finish options like tin-plating, resisting wear from moisture or oxidation. Their strong anchoring reduces stress on conductors, extending service life in heavy-use environments. This durability lowers your replacement frequency, protecting your budget over time.

What if weaker lugs limit my system’s power capacity and future upgrades?

Our lugs support high current loads, giving your systems the strength to handle today’s demands and tomorrow’s growth. The quad-hole design boosts mechanical stability, allowing you to push power further without connection issues. This capability future-proofs your setups, saving you from early overhauls or undersized constraints.
