Are the Pre-TeSys Overload and Contactors compatible with the current TeSys Line?

Issue:  
Can the LR2D Class 20 overload relays be direct mounted to the new TeSys contactors?

Product Line: 
 Tesys D contactors and overload relays

Environment:
Products sold and used in the United States
 
Cause: 
Replacing an older pre-tesys device
 
Resolution:
No. The bottom of the new TeSys contactor is made in such a way that the old LR2D overload relay can`t be mounted directly to it. Obtain a new LRD TeSys overload relay for direct mounting.
This also applies to old contactors with new overload relays, they will not mount properly and a new contactor should be obtained.
