Phoenix Contact 3036026 STTB 2,5-PE Protective conductor double-level terminal

The STTB 2,5-PE is a Phoenix Contact protective conductor double-level terminal block for grounding and equipotential bonding in industrial control systems. It provides four spring-cage connections across two levels, accepting rigid conductors from 0.08 mm² to 4 mm² at a nominal cross section of 2.5 mm². The green-yellow terminal mounts directly on NS 35/7.5 or NS 35/15 DIN rail, establishing low-resistance ground contact without additional wiring.
