TeSys LC1K contactor, 9 A AC-3, 24 VDC coil
The Schneider Electric LC1K09106FLS207 is a 3-pole contactor from the TeSys range, rated for motor control in AC-3 and AC-3e duty up to 9 A, and for resistive loads (AC-1) at 20 A. The 24 VDC coil includes integral suppression, so no external flyback diode is needed — one less component to mount and verify on the panel layout. Mechanical durability is rated at 30 million cycles, and electrical durability at 1.3 million cycles at 9 A AC-3 up to 440 V. That puts the wear-out point well beyond typical machine life for moderate-duty applications like conveyors, pumps, and small compressors — a solid fit for a production line where unplanned downtime is the metric that matters.
Built-in 1 NO instantaneous auxiliary contact covers basic feedback or interlocking. If you need more, the TeSys K range offers add-on auxiliary blocks that clip onto the front without extra wiring space.
The AC-1 rating (20 A) covers resistive loads like heaters. For signalling circuits, the minimum switching capability is 5 mA at 17 V, which means it can reliably switch PLC-level dry contacts without needing a separate interface relay. Safety reliability is quantified: B10d of 1,369,863 cycles at nominal load per EN/ISO 13849-1. That's the number of operations before 10% of a sample population fails dangerously — useful for SIL/PL calculations in safety-related control circuits.
