Intercable ICAL240V puristusliitinholkki 240 mm² RM/SM, 300 mm² SE, paljas kupari

Electrical installers and panel builders working on low-voltage power distribution often need a reliable way to join large copper conductors without soldering or bolted lugs. The Intercable ICAL240V compression connector sleeve solves that challenge: it accepts 240 mm² round stranded (RM) or sector stranded (SM) conductors, as well as 300 mm² solid sector (SE) conductors, and is crimped with standard hexagonal or indent dies. The bare electrolytic copper body ensures excellent conductivity and long-term corrosion resistance in dry indoor environments.

Key specifications

• Connector type: Compression sleeve (butt connector)
• Conductor cross-section: 240 mm² (RM/SM), 300 mm² (SE)
• Material: Electrolytic copper (E-Cu), min. 99.9% purity
• Surface: Bare (untreated)
• Insulation: Uninsulated
• Connection method: Crimp / compression
• Length: 90 mm
• Outer diameter: 28 mm
• Inner diameter (for 240 mm² conductor): 21.5 mm
• Number of crimp indents: 2
• Max. operating temperature: 105 °C
• Standard compliance: IEC 61238-1 Class A

Why choose it

This sleeve is machined from high-purity electrolytic copper, which delivers conductivity close to that of solid copper conductors and minimizes hot spots at the joint. The two-indent crimp pattern provides a secure mechanical and electrical connection that withstands vibration and thermal cycling. Because the sleeve is uninsulated, you can apply your own heat-shrink or tape to match the insulation class of the installation. Its compact 90 mm length fits easily into junction boxes and cable ducts.

Ideal use cases

• Joining large copper conductors in low-voltage distribution panels
• Creating permanent, maintenance-free connections in industrial wiring
• Extending or repairing 240 mm² and 300 mm² copper cables
• Applications requiring compliance with IEC 61238-1 Class A standards

Good to know

For best results, use a hexagonal or indent crimping tool with dies matched to the conductor size. The sleeve is uninsulated, so apply insulation after crimping according to the installation's voltage class. Store in a dry environment to preserve the bare copper surface.
