Product Information
Full details
The Phoenix Contact 3200072 is an insulated bootlace ferrule designed for electrical professionals and hobbyists looking to ensure reliable, high-conductivity wire terminations. Ideal for 2.5mm² wire applications, it prevents strand fraying and provides a secure, permanent connection in terminal blocks. While it offers excellent durability and corrosion resistance, users must ensure they are using the correct crimping tool profile compatible with its specific 18mm pin length to achieve a professional-grade finish.

FAQs
What wire size is this ferrule designed for?
This ferrule is specifically designed for 2.5mm² cross-section wires.
Does it meet international standards?
Yes, it conforms to DIN 46228-4: 1990-09 for dimensions and the French NF C 63-023: 1994-02 for color coding.
Can this be used with solid core wire?
Ferrules are generally intended for stranded wires to bundle strands together. They are typically not required or recommended for solid core conductors.
What is the total length of the component?
The total length of the 3200072 ferrule is 24mm, with a sleeve length of 18mm.
What material is the sleeve made of?
The metal sleeve is made from high-quality soft tin-plated electrolytic copper.
How many pieces come in one pack?
Each pack contains 100 units.
Troubleshooting
Ferrule slips off the wire after crimping
Verify that the wire gauge is exactly 2.5mm² and that the stripping length is sufficient to reach the back of the ferrule collar.
Crimped ferrule does not fit into the terminal block
Check if you are using the correct crimp profile. Some tools may create a square or hexagonal shape that might be too wide for specific narrow terminals; ensure your crimp profile matches the manufacturer requirements.
Plastic collar cracks during crimping
Ensure the crimping tool is properly calibrated. Too much pressure or an misaligned die can stress the plastic insulation.
Pros and Cons
Pros
- High conductivity due to tin-plated copper
- Reliable, clean termination prevents wire fraying
- Easy identification with standard grey color coding
- Consistent, standard-compliant dimensions
Cons
- Requires a specific crimping tool
- Single-use component once crimped
- Not suitable for wires outside the 2.5mm² specification
Setup, Compatibility & Care
To install, first strip exactly 18mm of insulation from your 2.5mm² wire to match the ferrule sleeve length. Insert the wire strands into the ferrule until they reach the base of the plastic collar. Place the ferrule into the corresponding die of your crimping tool and apply full pressure until the tool mechanism releases. Ensure the terminal block is rated for 2.5mm² conductors to maintain proper fit. Store these ferrules in a dry environment; although they are corrosion-resistant, excess moisture or industrial chemicals in storage can prematurely oxidize the tin plating.
