4mm² Grey Insulated Ferrules – Standardized and Reliable Connections for Industrial and Residential Installations
The 4mm ferrules with a length of 12mm and grey insulation are an indispensable connection element in modern electrical engineering. They are used for clean and secure termination of fine-stranded conductors, protecting them reliably from mechanical damage and conductor spread. The ferrule is optimized for processing with crimping tools and is suitable for both manual and automated applications. In installations with high demands on safety and durability, 4mm ferrule ensures consistently good electrical contacts – whether in switchboard construction, terminal block assembly, or equipment connections.
Technical Features
The ferrule meets the requirements of important European and international standards. It is REACH- and RoHS-compliant, confirming its environmental compatibility. Furthermore, it is UL-certified, making it approved for export products and international installations. This 12 AWG ferrule is also suitable for use in a wide range of applications, ensuring reliable connections and compliance with global standards.
With its grey insulation according to the updated standards DIN 46228 T4 and the German color code (B), it ensures safe identification of the conductor cross-section during assembly, preventing errors during terminal connection. Thanks to standardized dimensions, processing with automatic crimping machines is also easy – ideal for mass production. This bootlace ferrule 4mm2 is particularly suitable for fine-stranded conductors, ensuring a secure and reliable connection.
Applications
The 4mm bootlace ferrules are especially suitable for use in electrical installations where a standardized conductor connection is required. Typical applications include:
- Connections in distribution cabinets
- Wiring of terminal blocks
- Connection of devices, sensors, and actuators
- Wiring in switchboards and machines
- Photovoltaic systems, where vibration-resistant connections are necessary
- Control and automation technology
Especially in industrial environments, where vibration resistance, re-connectability, and corrosion resistance are required, the ferrule 4mm2 grey is a reliable choice. It also supports the standardized color coding of wire ends in complex wiring systems.
Conclusion
The insulated 12mm ferrule in grey is the perfect solution for installers who rely on standardized, safe, and time-saving electrical connections. Thanks to high-quality materials, precise manufacturing, and standardized color coding, it meets all the requirements of modern connection technology. The grey 4mm cable ferrules enable safe termination and provide long-term protection for stranded conductors – both in residential installations and industrial environments. Whether for switchboard construction, machine wiring, or photovoltaic systems – with this ferrule, you choose reliability and quality.
