Advantages
Globally recognized: Internationally proven screw connection
Maintenance-free and vibration-resistant thanks to the patented Reakdyn principle
Convenient separation of circuits through the implementation of knife disconnection
Space savings and flexibility with the connection of two identical conductors
Long-term stable connections with the use of high-quality materials
Low self-heating due to high contact forces
Maximum efficiency in the smallest space – thanks to integrated level bridging, the connections are connected across levels
