It draws 805 VA inrush at 50 Hz (cos φ 0.3) and settles to 55 VA holding power — the thermal dissipation lands between 18 and 24 W at 50 Hz, so the contactor enclosure needs to shed that heat in a panel. Coil resistance measures 0.84 Ω at 20 °C, and the inductance of the closed circuit is 0.14 H. The coil has no built-in suppressor module — if the control circuit drives inductive loads nearby, you will want an external RC snubber or varistor across the coil to limit voltage spikes on dropout. ## Operating characteristics and duty cycle Closing time is 20 to 35 ms; opening takes 7 to 15 ms. The coil holds in across 0.85 to 1.1 times Uc at 55 °C, and drops out between 0.35 and 0.55 Uc — that dropout margin is wide enough to ride through brief sags without nuisance tripping. Schneider Electric lists the LX1FG052 as obsolete.","metaTitle":"TeSys LX1FG052 Contactor Coil, 52 V AC 50 Hz, Obsolete","metaDescription":"TeSys F LX1FG052 contactor coil, 52 V AC 50 Hz, 18-24 W heat dissipation.
