The 42 V AC coil pulls 30 VA inrush, holds at 4.5 VA, and dissipates 1.3 W once sealed. That low hold-in power keeps the panel thermal budget tight, and the 1.3 W is easy to vent in a crowded enclosure. The screw-clamp terminals accept one or two conductors: 1.5…4 mm² solid, or 0.75…4 mm² flexible without ferrules, or 0.34…2.5 mm² with ferruled ends. That covers the common motor-circuit wire sizes in a 5.5 kW branch. The single built-in NC auxiliary contact handles signalling or interlocking without an add-on block. ## Durability and safety Mechanical durability is 10 million cycles — that's a decade-plus in a cycling conveyor or pump application. Electrical durability depends on load: 1.3 million cycles at 12 A AC-3 (motor), 300,000 cycles at 20 A AC-1 (resistive), and 20,000 cycles at 72 A AC-4 (plugging/inching). For safety circuits, the B10d value is 1,369,863 cycles under nominal load per EN/ISO 13849-1, which is the figure a safety integrator needs for SIL/PL calculations. The contactor carries EN/IEC 60947-4-1, UL 60947-4-1, CSA C22.2 No 60947-4-1, and JIS C8201-4-1 certifications — so it's accepted in European, North American, and Japanese panels without a separate approval run.","metaTitle":"Schneider Electric LC1K1201D7 TeSys K Contactor, 3P, 12A AC-","metaDescription":"Active TeSys K contactor, 3P, 12A AC-3/AC-3e at ≤440V, 42V AC coil, 1NC aux.
