The Schneider Electric LP1K12106BD is a 3-pole contactor from the TeSys K series, rated for 12 A in AC-3 and AC-3e utilisation categories at 440 V — that means it's sized for switching three-phase motor loads up to that current, not just resistive heating. The 24 VDC coil pulls in at 0.8 to 1.15 times the control voltage and drops out reliably at 0.1 times Uc, so a standard 24 VDC supply from a PLC or power supply will hold it. One normally-open instantaneous auxiliary contact is built in, enough for a feedback signal to the controller.
The lugs accept ring terminals with a 7 mm outer diameter, which is typical for this current class.
The AC-3 rating at 12 A, 440 V is the motor-switching figure that governs real-world fit — it's the current the contactor can make and break under full-load motor starts. The electrical durability at that duty is 1.3 million cycles, with mechanical durability at 10 million cycles. For safety-related circuits, the B10d value of 1,369,863 cycles (under nominal load) gives a reliability figure per EN/ISO 13849-1. The minimum switching capability is 5 mA at 17 V for signalling circuits, so it can handle low-level PLC inputs without contact-wetting issues.
Compliant with EN/IEC 60947-4-1 and -5-1, UL 60947-4-1 and -5-1, CSA C22.2 No 60947-4-1 and -5-1, and GB/T 14048.4. Flame retardance meets UL 94 V1 and NF F 16-101/102. That covers most industrial control panels in North America, Europe, and China without additional certification work.
