UT 4 is a universal terminal block with screw connection from Schneider Electric, with test socket screws on both sides, cross section: 0.14-4 mm², AWG: 26-10, width: 6.2 mm, color: Gray
The UT 4 is a universal terminal block with screw connection and test socket screws on both sides. It is designed for conductor cross sections from 0.14 mm² up to 4 mm² (flexible) or 6 mm² (rigid) and is suitable for applications up to 41 A and 1000 V.
The sheet lists detailed technical data including dimensions (6.2 mm width, 46.9 mm length), screw thread size (M 3), tightening torque (min 0.6 Nm), and various connection options such as ferrules with or without plastic sleeves. It also provides ratings for surge voltage, contamination class, and UL‑94 inflammability.
