Spring Connection Terminal Blocks

A spring-connection terminal block (spring-clamp terminal block) is a panel terminal block mounted on the mounting rail that holds the conductor by spring pressure instead of a screw. Because no screw is tightened, it speeds up wiring and is preferred in vibrating machine panels since there is no screw to loosen; two- and three-level housings fit more connection points into the same rail length. In this category, Onka OPK-C two-level and OPK-3K three-level terminal blocks are offered with a current rating of 24 A at 2.5 mm² cross-section, 32 A at 4 mm² cross-section and a voltage rating of 750 V, in housing colors such as gray, beige, blue, red and black; monoblock types are also available. Choose the cross-section by the conductor to be connected, the current rating by the circuit current, the level count by the space you can allot on the rail and the housing color by your circuit identification scheme. The top bridges, end stops and separator plates of the OPK series are in the Terminal Block Accessories and Spares category. A spring-connection DIN rail terminal block should not be confused with a spring push-button terminal block: a spring push-button terminal block is a splice terminal block that does not mount on a rail, while single-level spring-connection terminal blocks are in the DIN Rail Terminal Blocks category.

How to choose Spring Connection Terminal Blocks

A spring-connection terminal block (spring-clamp terminal block) is a panel terminal block mounted on the mounting rail that holds the conductor by spring pressure instead of a screw. Because no screw is tightened, it speeds up wiring and is preferred in vibrating machine panels since there is no screw to loosen; two- and three-level housings fit more connection points into the same rail length.

  • 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.
