It pulls 8 W of heat dissipation during continuous operation, so panel ventilation or spacing from heat-sensitive components matters in a crowded enclosure. Opening time runs 100 to 170 ms; closing is faster at 40 to 65 ms. That spread matters for sequencing — if you're coordinating interlocking or safety circuits, the slower opening side sets the window you need to guarantee separation. ## Control voltage limits and operating conditions The coil holds in from 85% to 110% of rated Uc (operational range) and drops out between 35% and 55% Uc at 55 °C. That dropout threshold is low enough that a sagging line won't cause nuisance dropouts, but verify your supply's brownout behavior against the 0.35 Uc floor — roughly 273 V AC on a 780 V nominal tap. Rated for ambient temperatures from -5 to 55 °C. Maximum cycling rate is 2400 operations per hour at 55 °C — enough for most motor-starting duty, but if you're running a high-speed pick-and-place or cam-driven load, check the thermal accumulation against the 8 W dissipation figure.","metaTitle":"Schneider Electric LX1FH7502 TeSys Contactor Coil, 780-800 V","metaDescription":"Active TeSys contactor coil LX1FH7502, 780-800 V AC 40-400 Hz, 8 W dissipation, 100-170 ms opening time.
