Terminal Connector End Clamp ALPAR Z4031 for Cable Cross‑Section 2×25–50 mm²

ALPAR Z4031 end terminal connector is designed to join and terminate two conductors with cross-sections from 25 to 50 mm². The clamp creates a stable mechanical and electrical connection suitable for power distribution, busbar terminations and cable transitions in industrial and electrical installations. Constructed to provide low contact resistance and secure conductor fixation, this terminal connector supports reliable current flow and reduces the risk of loosening under vibration or thermal cycling.

Advantages

The clamp ensures consistent contact pressure across both conductors and is engineered for ease of installation and long-term electrical performance. Its design minimizes contact resistance and supports stable connections in environments that require robust mechanical retention. The product is compatible with standard copper and aluminum conductors within the specified cross-section range and fits common terminal blocks and mounting arrangements used in distribution panels and switchgear.

Suitable for

• Power distribution and feeder cable terminations
• Busbar and panel connections
• Cable transitions between equipment and switchgear
• Industrial and commercial electrical installations

Key specifications

• Conductor accommodation: two conductors
• Supported cross-section: 25–50 mm² per conductor
• Function: end terminal connector / clamp for cable termination
• Electrical performance: designed for low contact resistance and secure electrical contact
• Mechanical characteristics: fixed clamp design for reliable retention under vibration and thermal changes

How to use

Strip the conductor insulation to the appropriate length, ensuring clean, oxide-free conductor ends. Insert both conductors fully into the clamp seating area, align them to achieve full contact, and tighten the fastening elements to the recommended torque for the conductor size. Verify mechanical retention and electrical continuity after installation and re-check torque after the initial thermal cycle where applicable. Follow applicable local electrical codes and safety procedures during installation and maintenance.

Usage recommendations

Use this connector with properly prepared copper or aluminum conductors within the specified cross-section range. Apply the correct tightening torque and consider anti-oxidation treatment or appropriate plating where dissimilar metals are connected to avoid galvanic corrosion. Periodically inspect connections in high-vibration or high-temperature environments to maintain low contact resistance and safe operation.
