SynCon® – Connecting Cables & Transformer Terminals SynCon® VTRK 4-Si
SynCon® VTRK 4-Si
The VTRK 4-Si has been specially developed for connecting molded safety transformers conforming to IEC 742/EN 60 742 / DIN VDE 0551-1 for low voltage halogen lamps. Mounting is considerably facilitated by this new development. This connection technology enables molding of the transformer to the terminal. A connection cross section of 4mm² can be realised for supply and return lines, despite the low height of only 12.4 mm.
The VTRKZ 4-Si terminal variant is also equipped with a solid strain relief element. In addition to this, two fuse terminal block variants are available to protect the transformers.
The VTRKZ 4-Si acts as the primary transformer protection, and the VTRKZ 4-Si/C protects secondary power circuits with max. 32 V. Both terminals are also available as special variants with LED displays.
The molded housing has a wall thickness of 1.2 to 1.9 mm.
The VTRK 4 and VTRKZ 4 are individually labelled with BN Zack strip.
