I am trying to locate and auxiliary contact for an isolator disconnect sold here on NEWARK.com p/n 33R0181 (manufacturer MULTICOMP, their p/n LBDI1253P). On the disconnect assembly itself, the molded lettering has "SALZAR". I have been told this is SALZAR of India, not the SALZAR of Germany, and that both companies make similar parts, but they are not interchangeable. Website searches of SALZAR state the aux contact is either a RAC16 or a RAC125 - with RAC125 being more likely the correct part number. I am asking for help in finding this aux contact for purchase through NEWARK.com or a suitable substitute that will work. Thanx!
