MTKD-NICRSI/NISI - Thermoelectric voltage terminal block pair

Thermoelectric voltage terminal block pair, TC type N, nom. voltage: 400 V, nominal current: 1 A, number of connections: 4, number of positions: 2, connection method: Screw connection, 1 level, cross section: 0.2 mm2 - 4 mm2, mounting type: NS 35/7,5, NS 35/15, NS 32, color: gray

  • These special terminal blocks are used to extend thermocouple equalizing conductors in corresponding measuring circuits
  • This ensures that no false thermoelectric voltages occur at the junctions of the thermocouple/terminal block/compensating line and that the basic values in accordance with EN 60584/DIN EN 60584 are observed
  • The equalizing conductors are made from materials which, up to temperatures of 200°C, have the same thermal characteristics as the corresponding thermocouples
