Terminal Block Accessories and Spares

Terminal block accessories are the jumpering, fixing, separating, feeding and marking parts that complete a row of terminal blocks lined up on a rail. They are used in panel building to join neighboring terminal blocks at the same potential, to hold the terminal block group in place so it does not slide on the rail, to separate different circuit groups and to number the connection points. This category includes plug-in and screw-type top jumpers, small, large, screwless and group-labeled end stops, mini terminal block end stops, separator plates, feed modules and terminal block labels; almost all of the products are Onka brand. Choose the accessory first according to the brand and series of the terminal block, then according to the terminal block cross-section, the number of poles to be jumpered and the fixing method (screw or screwless). The MRK, OPK and MPK designations in Onka product names indicate which terminal block series the part belongs to; because the parts are made in series-specific dimensions, compatibility with terminal blocks of other brands must be confirmed from the manufacturer's data. Colored end stops and separator plates make it easier to tell circuit groups apart by eye.
