Accessories for vacuum contactors
Siemens Accessories for vacuum contactors
Magnet coils, changeover contactors, vacuum interrupters and mounting parts for the 3TF57, 3TF68 and 3TF69 vacuum contactors.
Vacuum contactors have a very long electrical service life, but the coil, the auxiliary switch block and the interrupters themselves are consumables. Vacuum interrupters are supplied as a set of three tubes with mounting parts, the changeover contactors for DC economy circuits complete with resistor and connecting cable, the magnet coils optionally with switch-on electronics. In addition the mounting parts: base plates for reversing and star-delta assemblies, cable sets for the main circuit, locking elements for mechanical interlocking and terminal covers for mounting on 3UF18 transformers. Check the exact article number of the base device – the parts are not interchangeable between 3TF68 and 3TF69.
