If you have searched for the term , you are likely holding a faulty unit, designing a control panel, or trying to reverse-engineer a circuit. Understanding the top-side schematic of this block is critical because it dictates how normally open (NO) and normally closed (NC) contacts interact with the contactor’s mechanical linkage.
The LAD402P supports up to 3600 operations per hour with AC-15 loads, but verify against your contactor’s duty cycle. lad402p schematic top
Each pole has two screws (line and load). For NO-1: 13 (in) and 14 (out). Some older schematics label by pole only. If you have searched for the term ,
