This document describes the features and characteristics of the UT 4-MT universal terminal block, including reliable screw connection, test socket screws, applicable wire cross-section range, dimensions, etc.
The UT 4-MT is a universal terminal block with screw connection and test socket screws on both sides. It supports conductor cross sections from 0.14 mm² to 4 mm² (flexible) or up to 6 mm² (rigid) and is available in a gray PA‑insulated housing.
Technical data include a nominal current of 16 A, nominal voltage of 500 V, rated surge voltage of 8 kV, and UL‑94 V0 inflammability class. Physical dimensions are 6.2 mm width, 56.8 mm length, with heights of 47.5 mm (NS 35/7.5) or 55 mm (NS 35/15). The screw thread is M3 with a minimum tightening torque of 0.6 Nm.
