Why the complete code matters

Before ordering or energising 140NOM21200C, verify any unsupplied value in the current exact-product document.
Keep 140NOM21200C visible in the bill of materials, quotation and maintenance log. This reduces the chance that a near-looking part is selected by appearance alone. The shared image on this page does not establish the physical identity or ratings of 140NOM21200C.
