Do LC1K and LC1D have mirror contacts? Which ones are those?

Yes, if those contactors have built in or using ad on auxiliary, in the following circumstances:

TESYS model K contactors :

Contactors
Additive blocks
LC*K0601 to
LC*K1601
The 21-22 NC auxiliary contact is a mirror contact.
LA1KN
The contacts of the additive blocks are not mirror contacts, even when it is a NC contact.
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
No signification. (no auxiliary contact)
LP*K..004
LP*K..008
No signification. (no auxiliary contact)


TESYS model D contactors :

Contactors
Additive blocks
 
LC1D09 to
LC1D95
The 21-22 NC auxiliary contact is a mirror contact.
LADN
 
 
 
 
 
LAD8N
All the NC contacts of the additive blocks are mirror contacts.
Ex : The 61-62 contact of a LADN11.
 
 
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.

Remark:
 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 not 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 can not close.
The mirror contacts are used in safety applications, particularly with the safety relays PREVENTA.
The notion of mirror contacts concerns power contactors, IEC60947-4-1 standard.
