Transition splice 3-1 with screw connector 70–150 mm² CellPack 261443

The CellPack transition splice 3-1 with screw connector for 70–150 mm² conductors is a mechanical terminal designed to join three incoming conductors into a single outgoing conductor. Intended for industrial and commercial power distribution, the splice provides a stable electrical connection for high-current applications where robust mechanical and electrical contact is required.

Advantages

This screw-type transition splice offers a compact design that accommodates large conductor cross-sections from 70 to 150 mm², ensuring reliable current transfer and low contact resistance. The mechanical screw connection enables straightforward installation without specialized tools, while the construction is made for repeated tightening and secure clamping. The product supports efficient cable routing and simplifies jointing in multi-conductor networks.

Suitable for

• Power distribution panels and switchgear connections
• Industrial and commercial electrical installations
• Splicing multiple feeders into a single main conductor
• High-current cable routing and termination

Key specifications

• Compatible conductor cross-sections: 70–150 mm²
• Connection type: mechanical screw connector for three to one conductor transition
• Application: three conductors joined into one for high-current circuits
• Material and finish: designed for electrical conductivity and mechanical durability (manufacturer standard materials)
• Installation environment: indoor electrical cabinets and protected industrial spaces

How to use

Strip the insulation from each conductor to the length recommended for the connector, ensuring clean, undamaged conductor ends. Insert the three incoming conductors and the single outgoing conductor into their respective ports, position them so that the bare conductors make full contact with the clamping surfaces, and tighten the screws to the torque values recommended by the installer guidelines or the manufacturer's instructions. After tightening, verify mechanical retention and measure continuity and contact resistance as part of commissioning.

Usage recommendations

Use appropriate personal protective equipment and follow local electrical codes during installation. Ensure screw terminals are tightened to the correct torque and periodically inspect joints in high-vibration or high-load environments to maintain safety and performance.
