It is a service part — not a standalone component — intended to restore a worn or failed coil in an existing contactor assembly. The coil draws 560...660 VA inrush and only 8...10 VA holding, which means the control transformer sizing is driven by the inrush spike, not the steady-state draw. Opening time is 25 ms, closing 45 ms — fast enough for most motor switching but not for high-speed jogging applications. That rate is the thermal limit of the coil, not the contactor — exceeding it risks overheating the winding even if the contactor itself can cycle faster. The control circuit voltage is 346...360 V AC 40...400 Hz, a non-standard range that sits above the common 230 V or 400-480 V control transformer taps. Operational limits are 0.85...1.1 Uc at 131 °F (55 °C), so the coil holds in from roughly 294 V to 396 V. Drop-out occurs between 0.35...0.55 Uc, meaning the contactor releases somewhere between 121 V and 190 V — wide enough to avoid nuisance drop-out on a sagging line but deliberate enough to drop on a serious undervoltage. Heat dissipation runs 8.4...10.4 W continuous. In a crowded panel, that adds up — if multiple TeSys F contactors are side-by-side with this coil, the cumulative heat can raise the ambient above the 131 °F (55 °C) operating limit. Panel ventilation or derating may be needed. The coil has no built-in suppressor module. If the contactor drives inductive loads, an external RC snubber or varistor across the coil terminals is recommended to limit voltage transients that could damage the control transformer or PLC output.","metaTitle":"TeSys LX9FH3502 Contactor Coil, 346-360 V AC, Obsolete","metaDescription":"Obsolete TeSys F specific contactor coil LX9FH3502, 346-360 V AC 40-400 Hz low consumption.
