The following tables show which contactors have mirror contacts, and which contacts these are:

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 (To be discontinued end of 2026)	The 21-22 NC auxiliary contact of the factory mounted lateral block is a mirror contact.
LC1D115A and LC1D150A	The 21-22 NC auxiliary contact is a mirror contact.

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, standard IEC 60947-4-1.
