Phoenix Contact 3100059 Thermoelectric Voltage Terminal Block Pair

The Phoenix Contact MTKD-CU/CUNI (3100059) is a specialized terminal block pair used to extend thermocouple equalizing conductors within measuring circuits. These terminal blocks are crucial for maintaining accurate temperature readings by ensuring the equalizing conductors have the same thermal characteristics as the thermocouples, up to temperatures of 200°C. Featuring a screw connection, it accommodates conductors from 0.2 mm² to 4 mm² (AWG 24-12). Its compact design, combined with its robust construction and adherence to IEC 60947-7-1 standards, makes it suitable for a wide range of industrial applications where precise temperature compensation is essential. The terminal block's gray color and PA insulating material contribute to its durability and reliability in demanding environments.
