Terminal connector end clamp ALPAR Z403 for AsXSn cable 4×25–50 mm²

ALPAR Z403 is an end terminal clamp engineered for AsXSn power cables with four cores and conductor cross-sections from 25 to 50 mm². It secures cable ends mechanically and ensures a reliable electrical connection at termination points. The clamp is intended for use in industrial distribution systems, junction boxes and indoor or overhead routing where a firm, safe cable termination is required.

Advantages

The terminal connector end clamp offers stable mechanical fixation and consistent electrical contact across the specified conductor range. Its design accommodates four-core AsXSn cables with conductor sizes between 25 and 50 mm², reducing the need for multiple connector types. The clamp is compact and suitable for confined enclosures, enabling straightforward installation and a low-profile termination. Materials and contact surfaces are selected to provide corrosion resistance and durable conductivity under normal installation conditions.

Suitable for

• Termination of AsXSn 4-core power cables (25–50 mm²)
• Industrial and commercial distribution panels
• Junction boxes and cable glands
• Indoor and overhead fixed cable routing

Key specifications

• Cable type compatibility: AsXSn 4-core power cables
• Conductor cross-section range: 25–50 mm²
• Function: end terminal clamp providing mechanical fixation and electrical connection
• Suitable mounting: enclosure or terminal block attachment at cable termination points
• Construction: compact design for confined spaces; corrosion-resistant contact surfaces

How to use

Strip cable insulation to the appropriate length, taking care not to damage conductor strands. Insert each conductor into the corresponding clamp entry and tighten the securing screws or fasteners to the torque recommended by the installer’s practice or applicable standards. Ensure that conductors are fully seated and that the clamp provides firm mechanical restraint. After tightening, verify electrical continuity and check for correct insulation clearances before energizing the circuit.

Usage recommendations

Use this terminal connector for fixed installations with AsXSn 4-core cables in accordance with local electrical codes and installation standards. Select proper torque values for the securing fasteners, confirm conductor size compatibility, and maintain required creepage and clearance distances in enclosures. Regularly inspect terminations for tightness and signs of corrosion or overheating during scheduled maintenance.
