Features

• Provides connection for large conductor sections up to 50 mm² with enhanced current capacity.
• Reliable connection between copper and aluminum conductors with mechanical retention suitable for large sections.

Applications

• Distribution cabinets, industrial panels, power systems requiring high-capacity connections.
• Main line connections or sub-feed connections, mixed Cu/Al installations.

Usage recommendations

• Choice of conductor: respect the specific ranges (Cu 2.5–50 mm² / Al 6–50 mm²).
• Ferrules: use ferrules for flexible conductors to ensure uniform clamping.
• Tightening: apply the appropriate torque (4 to 12 Nm) according to conductor section.
• Mounting: install on DIN rail or surface-mounted according to configuration.
• Identification: use housing colors to identify phase, neutral and earth.
• Maintenance: regularly check connections, especially on large sections.
