SynCon® – Connecting Cables & Transformer Terminals SynCon® ZTRK 4, ZTRK 4/2 and ZTRK 4/3

The ZTRK 4 terminal with spring-cage connection and the SI-TRK fuse holder were developed for both direct mounting on bobbins with integrated mounting compartments and snap mounting on 2 x 10 mm und 2 x 35 mm aluminium transformer rails. The terminals cover the cross section range from 0.2 mm² to 4.0 mm².

A green/yellow variant without metallic contact to the contact surface and a fuse terminal block with identical shape are also available.

The terminal has a practical 2.3 mm test hole designed for the test plug. The SIH-TRK fuse holder can accommodate a 5 x 20 mm replacement fuse directly on the transformer.
