Video: What auxiliary contact modules are available for the LC1D and LC2D contactors?
Issue:
Auxiliary contact modules for the LC1D and LC2D contactors
Product Line:
Contactor and Starters - IEC
Environment:
North American Products
Resolution:
Select based on application requirements. Please note that the TeSys and Pre-TeSys auxiliary blocks are backward/forward compatible.
Front Mounting; maximum of 1 block per contactor:

Side Mounting; maximum of 1 block on each side for D2 Series and Tesys Series 40 through 80 amp contactors. Tesys 9 through 32, 115, and 150 amps contactors will accept 1 block and is limited to left side only. (*) DC control devices will not accept side mount auxiliaries.
(*) DC control exceptions that will accept one left side mounted auxiliary: LC1D115 & LC1D150.

Are the auxiliary contacts on the D line contactors overlapping?
Issue:
Do the Tesys D Contactors have make before break auxiliary contacts?
Product Line:
Tesys D contactors
Environment:
IEC Contactors
Cause:
Product Characteristics
Resolution:
Except for the LADC22, they are non overlapping (break before make). Thus, the normally closed contact opens before the normally open contact closes. The LADC22 has 1NO and 1NC overlapping contact (make before break).
