The LP1K09016BD3 is a TeSys K contactor from Schneider Electric, 3-pole with 3 NO main contacts and one NC auxiliary contact. Rated for AC-3 duty at 9 A up to 440 V, it also carries AC-1 and AC-4 utilisation categories. The 24 V DC coil includes a built-in bidirectional peak limiting diode suppressor, so no external flyback diode is needed on the coil drive.
The built-in coil suppression diode simplifies wiring and saves panel space compared to adding an external suppressor. Rated operational current is listed as 20 A, with specific AC-3 motor ratings at 9 A (≤440 V) and 16 A for other duty classes.
