## Your advantages 

- 

- 

- 

- 

- 

- 

- Simple wiring of very small, flexible conductors 

- No restriction on cross-sections when using conductors with ferrules 

- Meet the requirements of DIN EN 60947-7-2 or IEC 60947-7-2 for protective conductor connections 

- High level of safety thanks to the low-resistance connection to the ground potential via the top-hat rail 

- Direct contacting with the DIN rail enables fast, error-free grounding without additional wiring effort. 

- Full flexibility thanks to the standardized CLIPLINE complete bridging, marking, and testing accessories
