Frequently asked questions
Are the auxiliary contacts on the D line contactors overlapping?

Do the Tesys D Contactors have make before break auxiliary contacts?
Tesys D contactors
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).
