Compression and tubular cable lugs
Designed to be crimped on to a conductor to facilitate the termination of the cable
via the lug hole
A compression cable lug is larger and longer than a tubular cable lug.
The standard (DIN 46235) specifies the dimensions for all manufacturers of DIN compression cable lugs.
| Compression/tubular cable lugs | Material | Cross-sec. mm² | Stud hole (M) | Characteristics | Part number |
| HELU-S-RK-CU | Copper | 0.75 - 630 | 3 - 20 | Uninsulated Temperature up to +120°C | 907303 |
| HELU-S-RK-90-CU-UL | 6 - 300 | 5 - 20 | 907508 | ||

Ring cable lugs
Ring-type cable lugs offer maximum connection security by fully enclosing the bolt, ensuring stable performance even under vibration or movement. Featuring a compact, open-front crimp design with a round contact surface, they allow quick installation and reliable electrical contact.
These lugs are widely used in distribution boards, switchgear, and automotive applications where durability and safety are essential.
Fork-type lugs
Fork-type lugs enable fast and convenient installation, as they can be positioned under screw terminals without fully removing the screw.
This design saves time during wiring and maintenance, making them a practical choice for control panels and residential electrical circuits.
Pin-type cable lugs
Pin-type cable lugs are designed for push-in connections in terminal blocks or compact electrical assemblies.
They allow fast installation and are commonly used in compact or modular electrical systems where space saving and flexible wiring are required.
The twin version is designed to accommodate two conductors of the same cross-sectional area.
| Pin cable lugs | Material | Cable cross-section (mm²) | Pin length (mm) | Characteristics | Part number |
| B-PF | Copper | 0.5 - 95 | 17 - 55 | Uninsulated, temperature up to +120°C | 91556 |
| ADI-K | Copper | 1.5 - 16 | 17.5 - 25.5 | Many different colors | 91589 |
| ADI | Copper | 0.14 - 150 | 10 - 58 | 91850 | |
| ADI-B | Copper | 0.5 - 2.5 | 14 | 91912 | |

Frequently asked questions about cable lugs
Cable lugs are accessories used to connect or disconnect cables from electrical equipment, busbars, or other connection points, playing a critical role in electrical systems.
They are typically manufactured from copper or aluminum, or their respective alloys, to ensure excellent electrical conductivity and mechanical strength.
Cable lugs simplify the installation, maintenance, and repair of electrical systems. They allow:
- Connect two or more cables together
- Connect the cable to the circuit breaker, fuse holder, and electrical equipment.
- Ensure a secure, stable, and safe electrical connection during operation.
Copper cable lugs are suitable for:
- Copper conductor
- Applications requiring high electrical conductivity
- Control cabinets, switchgear, and industrial electrical systems
Aluminum cable lugs are specifically designed for:
- Aluminum wire
- Preventing contact corrosion when used with the correct conductor material
- Stable operation under thermal effects and varying electrical loads
Bimetallic cable lugs are used when aluminum conductors need to be connected to copper busbars or copper contact points. The bimetal design helps:
- Preventing electrochemical corrosion
- Ensure stable and durable technical connections
- Suitable for electrical systems with different conductive materials
