The Schneider Electric LC1K09016FLS207 is a TeSys K contactor, 3-pole, rated for AC-3 duty at 9 A up to 440 V, with a 110 V DC low-consumption coil that includes an integral suppression device. The 1.8 W hold-in power at 20 °C keeps the panel heat budget predictable — no extra snubber needed across the coil. It switches motor loads in control panels, mounted on a rail or plate. The 45 mm width and 58 mm height fit standard DIN-rail spacing, and the IP20 finger-safe enclosure meets VDE 0106 for panel-side handling.
Electrical durability is 1.3 million cycles at that 9 A AC-3 rating, so it handles frequent starts on a conveyor or pump without early replacement. For resistive loads (AC-1), it carries 20 A with 0.18 million cycles. Mechanical durability is 30 million cycles, meaning the contactor's mechanical life far exceeds its electrical life under load — a sign the design margin is in the armature and spring set, not the contacts. The 1 NC auxiliary contact is instantaneous, rated for signalling circuits down to 5 mA and 17 V, so it can switch PLC inputs or status lamps directly without a separate interface relay. Safety reliability is quantified: B10d of 1,369,863 cycles with nominal load per EN/ISO 13849-1, and 20 million cycles with mechanical load only. That gives a usable figure for SIL/PL calculations on a guarding circuit.
