Terminal Blocks
A terminal block is a connection element, mostly with an insulating body, that connects conductors to each other or to a circuit detachably, without soldering. It is used in electrical panels to connect field cables to the circuits inside the panel, in junction boxes to splice lighting and socket lines, and to bring grounding and neutral conductors together at a common point. This category includes screw and spring connection DIN rail terminal blocks, mini, fused and measurement-disconnect terminal blocks, plug-in and tabbed junction box terminal blocks, panel grounding and neutral terminal blocks, and accessories such as top jumpers and end stops. Most DIN rail terminal blocks and accessories are Onka brand; brands such as Gwest, Konsan and Isıso are available among the junction box terminal blocks. Choose the terminal block according to the cross-section of the conductor to be connected, the rated current and voltage of the circuit, the connection technique (screw, spring or plug-in), the mounting location (DIN rail, junction box or panel) and the color that will distinguish the circuits. Accessories such as jumpers, end stops and separator plates must be compatible with the terminal block's series; the MRK, OPK and MPK codes in Onka product names indicate the series the part fits.

How to choose Terminal Blocks
A terminal block is a connection element, mostly with an insulating body, that connects conductors to each other or to a circuit detachably, without soldering. It is used in electrical panels to connect field cables to the circuits inside the panel, in junction boxes to splice lighting and socket lines, and to bring grounding and neutral conductors together at a common point.
- 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.
