Phoenix Contact 3214657 PTTBS 1,5/S Double-level terminal block 16A

The Phoenix Contact PTTBS 1,5/S is a double-level terminal block from the PTS product family, combining two separate circuits in a single 3.5 mm wide unit rated at 500 V and 16 A. Push-in connection technology on both levels allows tool-free, vibration-resistant conductor termination across a range of 0.14 mm² to 1.5 mm². The compact design mounts on NS 35/7.5 or NS 35/15 DIN rail for high-density control cabinet installations.
