This coil is the energizing element that pulls in the contactor armature, enabling the main power contacts to close. For audit purposes, the inrush power draw is 350-400 VA at 50 Hz with a cos phi of 0.55, and the hold-in consumption drops to 20-30 VA at 50 Hz with a cos phi of 0.28. Sourcing is limited to the surplus and broker market. No direct replacement is listed by the manufacturer. ## Control Circuit Specifications The control circuit voltage is 110 V AC, with operational limits of 0.85 to 1.1 times Uc (93.5 to 121 V AC) at up to 55 °C. The drop-out voltage range is 0.25 to 0.7 times Uc (27.5 to 77 V AC) under the same temperature conditions. The inductance of the closed circuit is 1.48 H, which influences the inrush and hold-in current profile and should be considered when sizing control transformers or selecting suppression devices for the coil circuit.","metaTitle":"Schneider Electric LX1LD1109 TeSys Integral Coil, 110 V AC","metaDescription":"Obsolete TeSys Integral replacement coil, 110 V AC control voltage, 350-400 VA inrush.
