Klauke 553R buis-schroefverbinder, 16 mm², soldeergat, messing, vertind

The Klauke 553R tubular screw connector stands apart from typical alternatives by combining a robust screw terminal with an integrated solder hole, enabling both mechanical and soldered connections in a single compact component. This dual-connection design is particularly valuable in applications where vibration resistance or additional electrical integrity is required, such as control cabinets and distribution boxes. Its 16 mm² conductor capacity and electro-tinned brass construction ensure reliable performance in demanding electrical installations.

Highlights

• Dual connection: screw terminal and solder hole for versatile wiring
• Supports fine-stranded and solid conductors up to 16 mm²
• Electro-tinned brass body for corrosion resistance and conductivity
• Rated for up to 750 V AC/DC and 76 A
• Compact inline design for easy integration

In daily use

Electricians and panel builders will appreciate the 553R's straightforward handling. The M5 screw provides a secure mechanical clamp, while the solder hole allows for a permanent bonded connection when needed. Its uninsulated silver-tinned surface is ideal for applications where space is limited and a reliable, low-resistance joint is essential. The connector is free-hanging, making it suitable for inline splicing or junction points.
