Can the single pole LA1DN and LADN auxiliary contact module be mounted on the TeSys contactors?
ISSUE
In which contactors can the LA1DN and LADN auxiliary contacts be mounted?
PRODUCT LINE
Auxiliary contacts for the Tesys D line
ENVIRONMENT
Tesys D-Line and Tesys F
RESOLUTION
These contacts will only fit on the following contactors:
Front mount only for LC1D40 through LC1D115 devices and LC1D40A - LC1D65A.
Left side mount only to LC1F contactors
Will a single circuit auxiliary contact block, like a LADN10 or LADN01, fit onto the Tesys D09-D38 amp contactors?
Issue:
Identifying auxiliary contact blocks for Tesys D contactors
Product Line:
IEC contactors and starters
Environment:
Tesys D Auxiliary contact blocks
Cause:
single auxiliary contact block needed for use on a Tesys D line contactor
Resolution:
No, the single pole contact block will not fit . A LADN11,LADN20, LADN02 etc will fit. Anything with 2 auxiliary contacts in one block will fit.
