Dowells Copper Insulated Pin Terminal (CPI Series) is an EC-grade electrolytic copper, electro-tin plated, insulated crimp pin terminal for high-density electrical panel wiring. The integrated insulation sleeve prevents exposed wire ends from touching adjacent terminals in dense panel boards, eliminating short circuit risk. The solid cylindrical pin tip inserts smoothly into narrow terminal blocks, push-in connectors, and breakers. The compression crimp barrel gathers multi-strand flexible conductors into a solid cold-welded copper mass, eliminating wire splaying. Supplied in packs of 200 pieces, available in 4 variants covering cable cross-sections from 1.5 sqmm to 6.0 sqmm – select the correct item code for your wire size.
Key Features
Insulated sleeve: Eliminates exposed wire risk in dense panel boards – prevents short circuits and accidental contact
EC-Grade electrolytic copper: High-purity copper for minimal electrical resistance and maximum conductivity
Electro-tin plated: Full tin coating protects against moisture, rust, and oxidative corrosion
Solid cylindrical pin tip: Smooth insertion into narrow terminal blocks, push-in connectors, and breakers
No soldering required: Compression crimp creates a cold-weld bond – faster installation, no heat risk

Installation Notes
Important – Read Before Crimping
Use a ratchet-action crimping tool: A professional ratchet crimping tool locks the barrel correctly – standard wire pliers will not produce a reliable joint
Strip to correct length: Strip wire strands to the exact length of the internal metal barrel before insertion – under-stripping leaves insulation inside the crimp zone
Use colour-coded insulation boots: When routing multiple channels side by side, use the multi-coloured insulation sleeves to visually map separate power phases or signal blocks
