SynCon® – Connecting Cables & Transformer Terminals SynCon® TRK 2.5 and TRK 2.5-FS

TRK terminals can be selectively snap mounted on the 2 x 10 mm or 2 x 35 mm mounting rail and bobbins withintegrated mounting compartments. In addition to the groundterminal block, all insulation housings have a covering flap. Thisreveals the lateral open solder hook to facilitate the insertion andsoldering of winding ends and subsequent fingerproof covering in compliance with VBG 4. This type covers the cross-sectional range up to 10mm².With the exception of the TRK 10, the terminals are availablewith screw or screw and slip-on connections.

The TRK 4-SL yellow/green ground terminal block can beharmoniously connected to the remaining terminal types. It isscrewed to the laminated core together with the mounting rail.

All TRK terminals are designated with the marker pin BN-TRK.
