It's the service part you pull when the original coil on an Integral contactor or starter fails — the coil itself is the only component swapped, not the entire contactor block. ## Electrical characteristics for commissioning Coil resistance measures 0.987 Ohm at 68 °F (20 °C) — a cold-check value to verify against a known-good coil during troubleshooting. Inrush power draws 420...500 VA at 60 Hz with cos phi 0.55, settling to 24...36 VA hold-in power at 60 Hz cos phi 0.28. That inrush-to-hold ratio is typical for AC-operated contactor coils; the control transformer feeding this circuit needs to handle the inrush without voltage sag. ## Operating voltage window The control circuit voltage limits are specified at 0.85...1.1 Uc for operation (35.7...46.2 V AC) and 0.25...0.7 Uc for drop-out (10.5...29.4 V AC) at up to 131 °F (55 °C). This means the coil will pick up reliably at 85% of nominal and won't drop out until voltage falls below 70% — a standard margin for industrial AC control circuits.","metaTitle":"TeSys LX1LD042 Coil, 42 V AC 50 Hz, Active Production","metaDescription":"TeSys LX1LD042 replacement coil for Integral contactors. 42 V AC 50 Hz control circuit, 0.987 Ohm coil resistance, 420-500 VA inrush.
