It operates on a 20...22 V DC control circuit and is classified as a low-consumption coil, drawing 550 VA inrush and 31 VA hold-in at 68 °F (20 °C). This coil is built without a built-in suppressor module, so you'll need to add external flyback suppression (diode or RC snubber) across the coil terminals if driving from a PLC or solid-state output — otherwise the inductive kick can take out the output driver. The 60 ms opening and 50 ms closing times are standard for a contactor of this frame size. The 20...22 V DC control circuit voltage is narrow — this coil is designed for a tightly regulated DC supply, not a floating battery or unrectified AC. The operational limits are 0.85...1.1 Uc up to 131 °F (55 °C), meaning it holds in from about 17 V to 24.2 V DC, but drops out between 0.3...0.5 Uc (6...11 V DC). If your control voltage sags below 17 V under load, the contactor drops out. Heat dissipation runs 15...18.3 W continuous. In a sealed panel with multiple contactors ganged, that adds up — plan the thermal budget accordingly. The mechanical durability of 10 Mcycles means it outlasts most contactors it goes into; the coil is rarely the wear-out item. Rated for up to 3600 cycles per hour at 158 °F (70 °C), which covers high-speed cycling applications like packaging or material handling. The ambient operating range is -5...55 °C (23...131 °F). ## Integration note This is a service part — it replaces the coil inside an existing TeSys F contactor, not a standalone panel-mount device. The control circuit accepts AC 40...400 Hz or DC low-consumption drive, so it works with either a transformer-based AC supply or a DC bus, but the 20...22 V DC rating means you need to match the supply voltage closely. No built-in surge suppression means the installer wires an external diode or varistor across the coil.","metaTitle":"TeSys LX9FK911 specific contactor coil, 20..22 V DC, low con","metaDescription":"Active TeSys F specific contactor coil LX9FK911, 20..22 V DC low consumption, 60 ms open/50 ms close, 10 Mcycles mechanical durability.
