Rittal 3455505 Morsetto a innesto per conduttori tondi 0,5-4 mm², grigio

In control cabinets and distribution boards, electricians need a reliable way to connect round copper conductors without tools. The Rittal 3455505 push-in conductor connection terminal snaps onto a 10x3 mm busbar or mounting plate, accepting solid or stranded round conductors from 0.5 to 4 mm². Simply strip 10–12 mm of insulation and push the conductor in – the spring clamp holds it securely.

Why choose it

The push-in connection eliminates the need for screwdrivers, speeding up wiring and reducing fatigue. The terminal is made of flame-retardant polyamide and tin-plated copper alloy for long-term conductivity. It is rated for 800 V and 32 A, making it suitable for many industrial control applications.

Ideal use cases

• Connecting round conductors in control cabinets
• Distribution boards and switchgear assemblies
• Retrofitting existing busbar systems

Good to know

The terminal is grey and designed for copper conductors only. It has a wide operating temperature range from -40 °C to +100 °C and carries VDE, UL, CSA, EAC, and cULus approvals.
