Terminal ferrule (tinned) Erko TE_4-12/100 for 4 mm² conductors, pack of 100

Erko tinned terminal ferrules TE_4-12/100 are crimp-style end sleeves designed for 4 mm² stranded conductors, supplied in a pack of 100. These ferrules provide a reliable electrical contact by consolidating conductor strands into a compact, corrosion-resistant termination suitable for panel wiring, terminal blocks and control cabinets in electrical installations.

Advantages

These tinned ferrules reduce contact resistance and protect stranded wire from fraying during insertion and tightening in screw or clamp terminals. The tin plating improves corrosion resistance and ensures consistent conductivity over time. Packaged in a set of 100, they offer a convenient quantity for routine electrical work and maintenance tasks.

Suitable for

• Electrical panel wiring and distribution blocks
• Terminal blocks and control cabinets
• Industrial machinery and control panels
• Field service, repair and routine electrical maintenance

Key specifications

• Conductor cross-section: 4 mm²
• Type: crimp-style end ferrule (tinned)
• Material: metal tube with tin plating for corrosion resistance
• Pack quantity: 100 pieces
• Suitable for stranded (flexible) conductors

How to use

Strip the conductor to the appropriate length, insert the stripped strands fully into the ferrule barrel and crimp with a suitable crimping tool matched to 4 mm² ferrules. After crimping, verify a secure mechanical hold and ensure the ferrule barrel sits flush in the terminal or clamp. Proper crimping prevents strand separation and provides a stable electrical connection.

Usage recommendations

Use a dedicated insulated ferrule crimper rated for 4 mm² sleeves and inspect crimp quality visually and mechanically. Avoid using pliers or improvised tools that can deform the barrel or cause loose connections. For environments with high humidity or corrosive atmospheres, ensure compatible materials and proper panel sealing.
