The coil is 24 V DC with a built-in bidirectional peak-limiting diode suppressor, so no external flyback diode is needed on the control side — that saves a component and a wiring step on the panel. AC-1 duty means it's designed for switching resistive loads — heaters, ovens, lighting banks — where the current and voltage are nearly in phase. The conventional free-air thermal current (Ith) is also 20 A at 50 °C, so the contactor is thermally rated for that current in open air. The LP1K120045BD3 mounts on printed circuit boards — not a DIN-rail footprint. That makes it a good fit for custom control boards, OEM machine controllers, or panel designs where the contactor is soldered or bolted directly to a PCB rather than snapped onto a rail. The four NO poles give you independent switching of up to four separate resistive load circuits, or you can parallel them for higher current on a single load — though the AC-1 rating per pole stays 20 A. The contactor is rated for 3600 operations per hour and 10 million mechanical cycles, so it's built for continuous-duty applications like packaging lines or conveyor heating zones. The LP1K120045BD3 carries approvals to EN/IEC 60947-4-1, UL 60947-4-1, CSA C22.2 No 60947-4-1, GB/T 14048.4, and JIS C8201-4-1. That covers the major global markets — North America, Europe, China, Japan — so it's accepted in export machinery and multi-region installations. The rated insulation voltage (Ui) is 690 V per IEC 60947-4-1 and 600 V per UL 508 / CSA C22.2 No 14, and the rated impulse withstand voltage (Uimp) is 8 kV, which is standard for overvoltage category III environments.","metaTitle":"Schneider Electric LP1K120045BD3 TeSys K Contactor, 20A AC-1","metaDescription":"Schneider Electric TeSys K contactor LP1K120045BD3, 4P (4 NO), AC-1 rated 20 A at 690 V, 24 V DC coil.
