Phoenix Contact 3045127 UT 4 RD Feed-through terminal block 32A 2-conductor Red

The Phoenix Contact UT 4 RD is a single-row feed-through terminal block rated for 1000 V and 32 A in red for colour-coded screw-connection wiring on standard DIN rails. Accepting rigid and flexible conductors from 0.14 mm² to 6 mm², it suits a wide range of signal and power distribution tasks across industrial, railway, and process engineering environments. It is mechanically and electrically identical to the standard grey UT 4, differing only in housing colour for circuit identification.
