The Schneider Electric LP1K09105BDTQ is a TeSys K series 3-pole contactor rated for 9 A in AC-3 and AC-3e utilisation categories at 440 V, with a 24 V DC coil. The coil draws 3 W inrush and hold-in at 20 °C, with no built-in suppressor module — you add the flyback diode externally.
The 9 A AC-3 rating governs motor switching; electrical durability is 1.3 million cycles at that load. For heavy inrush (AC-4, 54 A), durability drops to 20,000 cycles — expect shorter life on plugging or reversing duty. Mechanical durability is 10 million cycles, so the coil and armature outlast the contacts under light loads. The 24 V DC coil operates between 0.8 and 1.15 Uc (19.2–27.6 V) and drops out above 0.1 Uc (2.4 V) at 50 °C — verify your supply stays within that band, especially on long cable runs. Safety reliability is quantified: B10d of 1,369,863 cycles under nominal load per EN/ISO 13849-1, and 20 million cycles with mechanical load only. That places it in a defined risk-reduction path for safety-related stop circuits, though the contactor itself is not a safety device — it is a standard power contactor whose failure rates are documented.
Certified to EN/IEC 60947-4-1 (contactor), EN/IEC 60947-5-1 (control circuit), UL 60947-4-1, UL 60947-5-1, CSA C22.2 No 60947-4-1 and 60947-5-1, and GB/T 14048.4. Flame retardance meets V1 per UL 94 and Class C2 per NF F 16-101/102. IP2X finger protection on the enclosure.
