Phoenix Contact 3025189 SK 20 Shield connection terminal block

The Phoenix Contact SK 20 is a shield connection clamp for grounding cable shields directly on busbars, with a contact resistance of less than 1 mΩ. It accepts cables with outer diameters from 3 mm to 20 mm and connects via an M4 screw tightened to 0.8 Nm. The steel body and spring-loaded, large-surface pressure plate deliver reliable, low-resistance shield termination for control panel and industrial wiring installations.
