Heat dissipation sits at 1.3 W, which is modest for a panel with multiple contactors ganged on a DIN rail. Mounting is flexible: rail or plate. The screw clamp terminals accept 1.5 to 4 mm² solid or 0.75 to 4 mm² flexible without ferrules, and 0.34 to 2.5 mm² flexible with ferrules — covers the common control-panel wire sizes for this current class. AC-1 is the resistive utilisation category per IEC 60947-4-1; the same contactor would carry a lower current in AC-3 (motor) duty. The 110 A rated making and breaking capacity across 220–440 V gives it a solid fault-clearing capability for a part this size. Coil hold-in is reliable across 0.8 to 1.15 Uc (80 to 115 VAC at 20 °C), with drop-out at ≥0.20 Uc (20 VAC). The 30 VA inrush at 20 °C is the peak draw during pick-up; steady-state dissipation is the 1.3 W figure. No built-in suppressor module means you add your own RC snubber or varistor if driving the coil from a PLC output or if EMI suppression is needed.","metaTitle":"Schneider TeSys LC1K09004K7 Contactor, 20 A AC-1, 100 VAC Co","metaDescription":"Schneider Electric TeSys LC1K09004K7 contactor, 20 A rated operational current (AC-1), 100 VAC 50/60 Hz coil, 4 NO poles.
