What is the difference between the pre-Tesys and Tesys D line contactors?
IEC Telemecanique contactors
Tesys D line contactors
The pre-tesys D line contactors have been replaced by the new Tesys D line contactors
The pre-Tesys style of contactor included the auxiliary contact arrangement in the part number, for example the LC1D0911 is a 9 amp contactor with 1 normally open and one normally closed auxiliary contact, and the LC1D8010 is an 80 amp contactor with 1 normally open auxiliary contact and no normally closed auxiliary contacts. The current line of contactors do not include the auxiliary contacts in the part number, but automatically come with 1 normally open and 1 normally closed auxiliary contact; both the LC1D09 and LC1D80 would come with one of each.
