Standard DIN Rail Terminal Blocks

A standard DIN rail terminal block is a single-level feed-through terminal block that joins two conductors one-to-one with one input and one output connection point. It is the basic element of terminal block rows that carry field cables into the panel's internal wiring, and is used at points in control, signal and power circuits where a straight feed-through connection is needed. In this category, Onka OPK series push-in terminal blocks are listed in cross-sections such as 1.5 mm², 2.5 mm², 4 mm², 6 mm², 10 mm², 16 mm² and 35 mm², with rated currents such as 17.5 A, 24 A, 41 A and 125 A and a 750 V rated voltage. Choose the terminal block by conductor cross-section, a rated current that covers the circuit current, housing color for phase, neutral and control separation, and compatibility with bridges and end stops of the same series. Solid and ferrule-terminated stranded conductors are fitted into the push-in slot without tools. A feed-through terminal block with a yellow or green housing is not a yellow-green ground terminal block that makes conductive contact with the rail; for protective conductors, the types in the Ground Terminal Blocks category are used.

How to choose Standard Terminal Blocks

A standard DIN rail terminal block is a single-level feed-through terminal block that joins two conductors one-to-one with one input and one output connection point. It is the basic element of terminal block rows that carry field cables into the panel's internal wiring, and is used at points in control, signal and power circuits where a straight feed-through connection is needed.

  • Clarify whether the task is connection, cable routing, enclosure distribution or termination.
  • Match dimensions, thread standard, conductor cross-section and IP rating with the cable and panel.
  • Choose housing material and pack quantity according to the mounting environment.

Frequently asked questions

What is Standard Terminal Blocks and where is it used?

A standard DIN rail terminal block is a single-level feed-through terminal block that joins two conductors one-to-one with one input and one output connection point. It is the basic element of terminal block rows that carry field cables into the panel's internal wiring, and is used at points in control, signal and power circuits where a straight feed-through connection is needed.

What should I compare when choosing Standard Terminal Blocks?

Choose the terminal block by conductor cross-section, a rated current that covers the circuit current, housing color for phase, neutral and control separation, and compatibility with bridges and end stops of the same series.

Where can I find technical details for Standard Terminal Blocks products?

A feed-through terminal block with a yellow or green housing is not a yellow-green ground terminal block that makes conductive contact with the rail; for protective conductors, the types in the Ground Terminal Blocks category are used.
