The Schneider Electric LC1K0901M7TQ is a TeSys K 3-pole contactor rated for 9 A in AC-3 and AC-3e duty at 440 V, with a 220...230 V AC coil. It is designed for motor control and resistive load switching, certified to EN/IEC 60947-4-1, UL 60947-4-1, and CSA C22.2 No 60947-4-1.
The 9 A AC-3 rating at 440 V governs motor switching — this is the current the contactor can make and break under typical induction-motor starting conditions. The AC-3e rating extends that to energy-efficient motors with higher inrush. AC-1 at 20 A covers resistive loads like heaters. The coil pulls 30 VA inrush and holds at 4.5 VA at 50/60 Hz, with an operating range of 0.8...1.15 Uc and drop-out at ≥0.20 Uc. Mechanical durability is rated at 10 Mcycles, with electrical durability at 1.3 Mcycles under AC-3 at rated current. The maximum operating rate of 3600 cycles per hour sets the thermal limit for repetitive switching in a panel. Screw clamp terminals accept 1.5...4 mm² solid or 0.75...4 mm² flexible wire, single or dual.
The contactor carries fire resistance at 850 °C per IEC 60695-2-1 and flame retardance Class C2 per NF F 16-101/102, plus V1 per UL 94. Safety reliability is quantified with B10d = 1,369,863 cycles under nominal load per EN/ISO 13849-1.
