A professional connection solution for strong twin conductors
In practice, professionals know exactly how important a clean, mechanically stable and electrically safe connection between two conductors is – especially at larger cross-sections such as 2x4 mm². This is precisely what the twin bootlace ferrules 4mm2 were developed for. As an experienced installer or control-cabinet builder you know: when two strong fine-stranded conductors need to sit reliably in one terminal, you need more than standard quality. These twin bootlace ferrules 4mm2 deliver exactly that – precision, durability and standard-compliant colour identification in one well-thought-out product.
The generous interior offers room for two flexible conductors, each with a 4 mm² cross-section, which are permanently contacted by the robust metallic ferrule body. These double bootlace ferrules 4mm2 enable a stable connection with minimal space requirement. The overall length of 20.5 mm with a ferrule length of 12 mm ensures precise guidance in terminal blocks and devices, without loose or untidy transitions. The grey insulating collar additionally provides mechanical protection and serves for easy visual allocation – ideal for professional series installations and control-cabinet construction.
Technical features at a glance
This double bootlace ferrule 4mm2 is made of high-quality, soft-annealed Cu-DHP copper, known for its excellent conductivity. A tin coating of at least 3 μm permanently protects the surface against corrosion and contact resistance. The insulating collar is made of durable polypropylene, which withstands temperatures up to +105 °C – so the ferrule remains dimensionally stable and safe even under demanding conditions.
With its exact fit and reinforced wall thickness it ensures a secure crimp contact even under strong vibration or changing temperatures. The twin bootlace ferrules 4mm2 are designed to sit reliably even in dense terminal blocks or tight installation spaces.
Standard compliance & colour coding
Naturally, the bootlace ferrule 4 mm² grey insulated complies with the industry standard DIN 46228 Part 4, which precisely defines the requirements for insulated twin bootlace ferrules. The grey colour identification follows the French colour code (type A), which allows an unambiguous visual allocation of the cross-section – an enormous advantage during fault analysis or later service work.
In addition, the bootlace ferrule 2x4 mm2 is REACH- and RoHS-compliant and holds a valid UL certification, which also makes it attractive for international and cross-industry projects. Rely on tested quality – manufactured to strict German standards.
Typical areas of application
The twin bootlace ferrules 4mm2 are used wherever two strong conductors have to be guided, connected or further processed together:
- In industrial control cabinets with high current flow
- In building services, e.g. for distributors with a high load
- In machine controls or protective circuits
- In vehicle or plant construction
- In photovoltaic systems or energy management systems
Wherever safe, space-saving and traceable wiring matters, these bootlace ferrules are the right choice.
Conclusion
Double bootlace ferrules 4mm2 are the right choice for anyone who relies on tested quality, mechanical stability and standard-compliant workmanship when wiring. Manufactured in Germany, they meet the highest demands in industry, control-cabinet construction and demanding series installations – reliable, precise and field-proven.
