Crimp Ring Terminal Insulated Erko KOE_10-25/50 – 50 pcs, Cu, for 10–25 mm² conductors

Insulated ring crimp terminals Erko KOE_10-25/50 are copper (Cu) terminations supplied in a pack of 50, designed for use with conductors from 10 to 25 mm². Each terminal combines a ring-shaped end for bolted connections and an insulated sleeve to protect the conductor and reduce risk of accidental contact. These crimp ring terminals are intended for applications that require secure, low-resistance connections and good mechanical retention under vibration.

Advantages

The copper construction provides reliable electrical conductivity and corrosion resistance appropriate for many wiring tasks. The insulated sleeve improves safety by covering the crimped connection and helps prevent short circuits. The ring end enables secure fastening to studs or screw terminals, delivering a stable mechanical and electrical joint. Supplied as a pack of 50, the set is convenient for batch wiring and maintenance work.

Suitable for

• Automotive wiring where vibration-resistant terminations are required
• Industrial control panels and machinery connections
• Household electrical installations and appliance repairs
• Battery and power distribution bus connections with stud or screw terminals

Key specifications

• Material: copper conductor with insulated sleeve
• Conductor cross-section compatibility: 10–25 mm²
• Contact termination style: ring end for bolted or screw fastening
• Quantity in pack: 50 pieces
• Insulation: sleeve type providing basic electrical protection
• Typical use: crimp-type mechanical and electrical connection

How to use

Strip the conductor to the length recommended for the terminal barrel, insert the bare conductor into the terminal barrel until it seats fully, and crimp using an appropriate crimping tool sized for 10–25 mm² terminals to ensure a secure mechanical and electrical connection. Position the ring end over the stud or screw and fasten with the appropriate washer and nut or screw to the manufacturer's torque specification. Verify the crimp and the bolted connection for firmness and correct electrical contact before powering the circuit.

Usage recommendations

Use a calibrated crimping tool matched to the terminal size to prevent loose crimps or conductor damage. Choose the correct conductor stripping length and avoid overexposure of bare wire. For environments with high moisture or corrosive conditions, consider additional sealing or use of corrosion-inhibiting compounds on bolted joints. Inspect connections after initial operation and periodically during maintenance.
