Terminal cable lug ALPAR Z404 for 4×70–120 mm² conductors, end connector

ALPAR Z404 is an end terminal cable lug designed to terminate four separate conductors with cross-sections from 70 to 120 mm². It ensures a stable mechanical and electrical connection in low-voltage power installations and is intended for use where multiple large conductors must be joined or connected to busbars, busbars tails, distribution panels, switchgear or junction boxes. The construction supports reliable current transfer and reduces the risk of loose connections in high-current applications.

Advantages

The terminal lug offers a compact design that accommodates four conductors in a single solid end connector, enabling space-efficient terminations. Its dimensions and conductor range allow use with commonly applied 70–120 mm² cables without additional adapters. The product provides secure clamping and consistent electrical contact area to minimise heating and voltage drop under load. Materials and manufacturing ensure mechanical strength suitable for typical low-voltage power distribution tasks.

Suitable for

• Terminating four-core or grouped conductors in low-voltage distribution panels
• Connecting multiple conductors to busbars or switchgear terminal points
• Creating compact cable tails or feeds in junction boxes and control cabinets
• Applications requiring reliable current transfer for conductors 70–120 mm²

Key specifications

• Conductor accommodation: four conductors
• Supported conductor cross-section range: 70–120 mm²
• Type: end terminal / cable lug for multi-core termination
• Intended application: low-voltage power distribution and switchgear connections
• Design: compact multi-conductor lug for space-saving terminations

How to use

Strip each conductor to the recommended insulation removal length, insert all conductors fully into the respective entry of the cable lug, and ensure conductor strands are neatly gathered. Apply the manufacturer-recommended crimping or compression method using an appropriate die or tool for the specified conductor size range to achieve a gas-tight connection. After crimping, inspect the joint for proper compression and secure the lug to the terminal stud or busbar using the correct bolt and torque for the system. Follow local electrical regulations and safety procedures during installation.

Usage recommendations

Verify conductor material compatibility and use the correct crimping tool and die set rated for 70–120 mm² conductors. Confirm bolt size and torque values for the mating terminal to ensure reliable mechanical and electrical performance. Perform periodic inspections in high-load or vibration-prone installations.
