Functions and applications

• Function: enables connection of multiple circuits at a single point while ensuring mechanical retention and optimal conductivity between copper and aluminium conductors.
• Applications: intermediate distribution cabinets, industrial and commercial installations requiring reliable medium-power circuit distribution.
• Usage advice: respect the copper and aluminium cross-section ranges, use ferrules for flexible conductors, apply the specified tightening torque, mount on DIN rail or surface, and use color coding for circuit identification. Regularly check tightening condition and contact cleanliness.
