Do TeSys Deca & TeSys K contactors have mirror contacts? Which ones are those?
Yes, if those contactors have built in or using add on auxiliary contact blocks, in the following circumstances:
TeSys K contactors:
TeSys Deca contactors:
Please note: Even if the NC contacts of the front auxiliary blocks are mirror contacts, we recommend to use the NC contact of the base product. By being integrated to the base product, it can't be removed and offers the maximum of safety.
A mirror auxiliary contact is a NC auxiliary contact which reflects the state of the NO main contact. It means that if a main contact remains closed (welded contact for example), the mirror contact cannot close. The mirror contacts are used in safety applications, particularly with the Harmony XPS Safety Modules. The notion of mirror contacts concerns power contactors, IEC60947-4-1 standard.
TeSys K contactors:
| Contactors | Additional blocks | ||
| LC*K0601 to LC*K1601 | The 21-22 NC auxiliary contact is a mirror contact. | LA1KN | All the NC contacts of the additional blocks are mirror contacts. |
| LP*K0601 to LP*K1601 | The 21-22 NC auxiliary contact is a mirror contact. | ||
| LC*K0610 to LC*K1610 | There is no mirror contact. (a mirror contact can only be a NC contact) | ||
| LP*K0610 to LP*K1610 | There is no mirror contact. (a mirror contact can only be a NC contact) | ||
| LC*K..004 LC*K..008 | Not applicable as there are no auxiliary contacts | ||
| LP*K..004 LP*K..008 | Not applicable as there are no auxiliary contacts | ||
TeSys Deca contactors:
| Contactors | Additional blocks | | ||
| LC1D09 to LC1D95 | The 21-22 NC auxiliary contact is a mirror contact. | LADN** LAD8N** | All the NC contacts of the additional blocks are mirror contacts. The contacts of these auxiliary blocks are not mirror contacts, even when it is a NC contact. | |
| LC1D115 and LC1D150 | The 21-22 NC auxiliary contact of the factory mounted lateral block is a mirror contact. | |||
