It sits in the TeSys range, which covers motor starters and contactors across panel and machine builds. The coil draws 350...400 VA inrush at 50 Hz (cos φ 0.55) to pull the armature in, then settles to 20...30 VA hold-in (cos φ 0.28). That inrush spike matters for sizing the control transformer and the fuse or breaker feeding it — a transformer rated for the steady-state VA will sag on pull-in. Average DC resistance is 290.8 Ohm at 68 °F (20 °C). Useful for bench-testing the coil with an ohmmeter before installation — an open or shorted reading means a bad coil before you ever apply power. Operational voltage range is 0.85...1.1 Uc, and dropout occurs at 0.25...0.7 Uc at ambient up to 131 °F (55 °C).","metaTitle":"TeSys LX1LD660 Coil, 660 V AC 50 Hz, 290.8 Ohm","metaDescription":"Active TeSys LX1LD660 coil for 660 V AC 50 Hz control circuits. 290.8 Ohm resistance, 350-400 VA inrush.
