Why choose it

These ferrules are manufactured from high-conductivity electrolytic copper with a tin plating that resists corrosion and ensures low contact resistance. The polypropylene collar provides reliable insulation and strain relief, while the blue colour coding follows DIN 46228 standards for 2.5 mm² conductors. They are compatible with square or hexagonal crimping tools, producing a uniform, compact connection that fits easily into terminal blocks.

Ideal use cases

• Terminating stranded wires in industrial control panels
• Building wiring in distribution boards and switchgear
• Automation systems and PLC connections
• Electrical installations in machinery and equipment

Good to know

For best results, use a crimping tool matched to the ferrule size. The insulation collar is designed to withstand the crimping process without splitting. Store in a dry environment to maintain plating integrity. These ferrules meet RoHS and CE requirements, making them suitable for use in the European market.
