Rittal Connection Adapter 3pRX 9360210B 63mm max.70 mm² Clamping Space 13x5mm

Connecting large conductors to RiLine60 busbar systems demands a reliable, high-current interface that maintains safety and performance. The Rittal Connection Adapter 3pRX 9360210B solves this challenge by providing a robust 3-pole connection point directly on 60 mm busbar spacing, engineered for conductors up to 70 mm². Its compact clamping space of 13 x 5 mm accommodates substantial cable lugs or busbar links, ensuring a secure and efficient power distribution in industrial control panels and switchgear assemblies.

Who is it for

This adapter is intended for panel builders, electrical engineers, and maintenance technicians who work with Rittal RiLine60 busbar systems. It is ideal for applications requiring high current ratings up to 250 A and operating voltages up to 690 V AC, such as motor control centers, power distribution units, and large machinery. If you need a dependable, screw-terminal connection for heavy conductors without complex tooling, this adapter is a practical choice.

Tips

Ensure the busbar system is de-energized before installation. Strip conductor insulation to the appropriate length and insert fully into the clamping space, then tighten the screw terminal to the recommended torque. For optimal performance, periodically check terminal tightness and inspect for signs of overheating or corrosion, especially in high-vibration environments.
