Insulated Crimp Connector Klauke 680 WS for 1.5–2.5 mm² conductors

Klauke 680 WS is an insulated crimp connector engineered for use with single or stranded electrical conductors of 1.5–2.5 mm² cross-section. Designed to provide a compact, mechanically robust and electrically secure termination, this insulated sleeve ensures reliable contact after proper crimping and offers insulation to reduce the risk of short circuits. It is intended for wiring tasks, terminal block connections and general electrical installations where a neat, repeatable conductor termination is required.

Advantages

The insulated design gives mechanical protection and electrical insulation, improving safety in confined wiring spaces. Its barrel geometry and internal surface are optimized for consistent crimping results with compatible crimping tools, producing a low-resistance contact and durable mechanical retention. Compact dimensions allow use in tight terminal strips and junctions without excessive bulk. The component is suitable for repeated standard electrical installation practices and supports straightforward, time-efficient terminations.

Suitable for

• Termination of single or stranded copper conductors with cross-section 1.5–2.5 mm²
• Connections in terminal blocks and distribution strips
• General building wiring, lighting circuits and control panels
• Field service and maintenance work requiring compact insulated terminations

Key specifications

• Conductor cross-section: 1.5–2.5 mm²
• Insulated sleeve for electrical protection
• Designed for manual or powered crimping tools compatible with insulated ferrules
• Compact barrel length for space-constrained terminals
• Material: conductive metal barrel with insulating sleeve (polymeric insulation)

How to use

Strip the conductor to the recommended insulation strip length so that the bare conductor fully inserts into the metal barrel. Insert the conductor into the crimp connector until the insulation butts against the sleeve. Use an appropriate crimping tool matched to insulated ferrules of this size and perform the crimping operation according to the tool manufacturer’s instructions to achieve a secure mechanical and electrical connection. After crimping, inspect the joint for proper compression and absence of exposed strands; give a gentle pull test to confirm retention.

Usage recommendations

For reliable results, select a crimping tool specified for insulated ferrules in the 1.5–2.5 mm² range and follow standard electrical installation practices. Avoid overheating the insulation and do not reuse deformed connectors. Verify compatibility with conductor type and terminal clamping method prior to installation.
