Your advantages

The special clamping nuts can be actuated with a normal screwdriver

Quick and easy connection with fold-up hinged covers which hold the clamping nuts captive. With the covers folded open, the bolt is free to accept the cable lugs

After closing and engaging the covers, the clamping nut automatically aligns with the threaded bolt and can be tightened easily.

The screws are secured against loosening by captive spring-loaded spacers

Large-surface labeling options in the terminal center and above the terminal points

Easy bridging and potential distribution using the patented plug-in bridges from the CLIPLINE complete system

The use of the switching lock effectively prevents unintentional switching

Testing with the standardized test adapters and test plugs of the CLIPLINE complete system

The hinged cover cover the live metal parts including the insulated cable lugs in the clamping area so that they are touch proof
