Phoenix Contact 3031380 ST 4-PE Spring-cage protective conductor terminal block

The Phoenix Contact ST 4-PE is a spring-cage protective conductor terminal block for reliable PE terminations in industrial switchgear and control panels. Rated at a nominal cross section of 4 mm², it accepts rigid conductors from 0.08 mm² to 6 mm² and mounts directly on NS 35/7.5 or NS 35/15 DIN rails, providing grounding without additional wiring.
