RT 8 BU - Bolt connection terminal block
Feed-through terminal block with bolt connection method, cross section: 2.5 - 35 mm2, AWG: 14 - 2, width 20.2 mm, color: blue
- 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
- Tested for railway applications
