It operates on an AC control circuit at 190...250 V AC, 40...400 Hz, drawing 650 VA inrush (cos φ 0.9) and 10 VA holding (cos φ 0.3). The inrush resistance is 58.4 Ω at 68 °F; the holding resistance climbs to 1366 Ω at the same temperature, which is the normal behavior of an AC coil's series impedance shifting as the armature seals. Opening time is 100...170 ms; closing time is 40...65 ms. Maximum operating rate is 2400 cycles per hour at 131 °F (55 °C). The coil dissipates 8 W at 40...400 Hz. It comes without a built-in suppressor module, so an external RC snubber or varistor is needed across the coil if the control circuit drives inductive loads or a PLC output. ## Control voltage limits and dropout behavior The coil holds in at 0.85...1.1 Uc (161...275 V AC) and drops out at 0.35...0.55 Uc (66...137 V AC) at 131 °F. That dropout range is wide — expect the contactor to fall out somewhere between 35% and 55% of rated voltage. If your control transformer sags under inrush from multiple coils, check that the trough stays above 66 V AC or the contactor may drop out unexpectedly.","metaTitle":"TeSys LX1FH1902 contactor coil, 190-250 VAC, obsolete","metaDescription":"Obsolete TeSys F contactor coil LX1FH1902, 190-250 VAC 40-400 Hz.
