The LAD402P supports up to 3600 operations per hour with AC-15 loads, but verify against your contactor’s duty cycle.
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. lad402p schematic top
