The AC-1 rating of 20 A at 440 V defines the continuous resistive load it can handle — think heater banks, lighting, or transformer primaries. The 4 NO pole arrangement gives four independent switching paths, all normally open, so it suits applications requiring simultaneous make of multiple load circuits. The coil operates across 0.85...1.1 Uc at 50/60 Hz and drops out at ≥0.10 Uc, which is a standard tolerance for 220 VAC control supplies. Mechanical durability is 10 Mcycles, and electrical durability is 0.16 Mcycles at 20 A AC-1 ≤ 690 V — that electrical life figure is the one to watch if the contactor cycles frequently under load. ## Silent operation and safety data This is a silent contactor — the coil technology includes an integral suppression device that reduces audible hum, a useful feature in noise-sensitive environments like HVAC zones or hospital equipment rooms. For safety circuit integration, the contactor carries a B10d of 1,369,863 cycles at nominal load per EN/ISO 13849-1, and 20,000,000 cycles with mechanical load only. Minimum switching is 5 mA at 17 V for the control circuit, so it can handle low-level PLC outputs without issues. ## Mounting and termination Mounts on plate or DIN rail — the 45 mm width (1.8 in) fits standard 45 mm rail spacing. Screw-clamp terminals accept solid wire from 1.5 to 4 mm² (single conductor) or flexible with cable end from 0.34 to 2.5 mm². Two conductors per terminal are allowed with appropriate derating. The compact footprint (57 mm depth, 58 mm height) leaves room for adjacent devices in a crowded panel. Flame retardance meets Class C2 per NF F 16-101/102 and V1 per UL 94. These approvals support use in rail, industrial control, and general electrical equipment where flammability and thermal endurance are specified.","metaTitle":"TeSys K LC7K09004M7TQ Silent Contactor, 4P, 20 A AC-1, 220 V","metaDescription":"TeSys K LC7K09004M7TQ silent contactor, 4 NO poles, AC-1 20 A at 440 V, 220 VAC coil with integral suppression.
