It is the part you swap when the original coil opens or the insulation breaks down — not a contactor body, just the electromagnetic actuator that pulls the main poles in. This coil carries no built-in suppressor module, so you need an external RC snubber or varistor across the coil terminals if the PLC output driving it is solid-state or if you are seeing noise on the 24 VDC control bus. The datasheet field note: the inrush power hits 650 VA at cos φ 0.9, then drops to 10 VA holding at cos φ 0.3 — that is a 65:1 ratio, which means the coil driver must handle the surge without dropping out the holding current. Opening time is 100...170 ms; closing is 40...65 ms. That spread matters when you sequence contactors in a motor-reversing or star-delta start: the slower opening means you need an interlock delay long enough to guarantee the opening contactor has fully cleared before the closing one picks up. At 2400 cycles per hour at 131 °F (55 °C), the coil can cycle every 1.5 seconds — fast enough for most conveyor jogging or press indexing, but not for high-speed pick-and-place where you need a DC coil or a dedicated fast-switching contactor. That is the contactor frame's life, not the coil's — the coil itself can fail earlier from thermal stress if the ambient stays near the 131 °F (55 °C) ceiling or if voltage sags cause it to chatter. The average coil resistance at 20 °C is 217 Ω inrush, 4631 Ω holding, which tells you the holding current is about 78 mA at 360 V — low enough that a standard PLC relay output can hold it, but the inrush current of 3 A peak is what burns marginal contacts.","metaTitle":"Schneider Electric LX1FH3502 TeSys F Contactor Coil, 328-360","metaDescription":"TeSys F contactor coil LX1FH3502, 328...360 V AC 40-400 Hz.
