HellermannTyton tinned copper screw connector 6-50mm² 650-ST-ML (435-01510)

The 650-ST-ML screw connector from HellermannTyton joins copper conductors from 6 to 50 mm² with a reusable, vibration-resistant connection. Unlike crimp lugs, it requires only a hex key for installation and can be removed and reused without damaging the conductor. The tinned copper body resists corrosion and maintains low contact resistance over time.

Highlights

• Connects copper conductors from 6 to 50 mm²
• Reusable screw terminal design
• Tinned copper for corrosion resistance
• High vibration resistance
• Uninsulated for use in controlled enclosures

In daily use

This connector suits maintenance and installation work where a reliable, inspectable joint is needed. The screw clamp allows fast assembly and disassembly, and the tinned surface withstands humid or mildly corrosive environments. It is rated for system voltages up to 1000 V AC/DC, depending on the installation.
