These special terminal blocks are used to extend thermocouple equalising conductors in corresponding measuring circuits
The equalising conductors are made of materials which, up to temperatures of 200°C have the same thermal characteristics as the corresponding thermocouples
This ensures that no false thermoelectric voltages result at the junctions of the thermocouple/terminal block/equalising conductor and that the basic values according to EN 60584/DIN EN 60584 are adhered to

This feed-through terminal block from Phoenix Contact is designed for connecting thermocouple equalising conductors. It can accommodate wires ranging in size from 24 to 12AWG (American Wire Gauge), making it a versatile option. Thanks to its screw termination method, you can quickly and securely attach the wires to the terminal.
With its nominal voltage rating of 400V, this terminal block is suitable for use with heavy-duty equipment. As it has compact dimensions of 46 (length) x 10.4 (width) x 40mm (height), it's suitable for use in setups where space is limited. Polyamide insulation material provides protection against electric shock for safe handling. You can easily mount this terminal block on a DIN rail using the quick-mount end clamp. This type of terminal block is commonly used for instrumentation and temperature management applications.

• Low maximum power dissipation of 0.77W for efficient operation
• Flammability rating of UL94V0 means burning stops within 10 seconds for safety in the event of a fire
• Light weight of 16.35g to minimise strain on your equipment
