SynCon® – Connecting Cables & Transformer Terminals SynCon® TRKS 4, TRKSD 4 and TRKS 4/3

This type family has been developed for direct assembly on the coil body with integrated installation chambers. All terminals can also be snapped onto aluminium transformer rails 2 x 10 mm and 2 x 35 mm in size.

The type series includes:

  • Single, double and triple terminals with screw connections
  • Single and double terminals with combined screw/push-on blade connections
  • Green/yellow PE terminals for screw connecting and welding to the core stack
  • Fuse terminals for the relevant 5 x 20 mm, 5 x 30 mm and 6.3 x 32 mm cartridge fuse links
  • Single, double and triple terminals with a connection capacity of 10 mm2
