That inrush-to-hold ratio matters for DC-supply sizing: the coil draws a heavy initial pulse, then settles to a fraction of that. The control circuit accepts both AC (40-400 Hz) and DC supplies, but the voltage range is DC-only — 28-31 V DC operational, with dropout between 0.3 and 0.5 Uc (roughly 8.4-15.5 V DC). ## Switching timing and thermal budget Opening takes 60 ms, closing 50 ms — standard for a DC-operated coil of this size. The coil dissipates 15-18.3 W continuously, which means the panel designer needs to account for that heat in a confined enclosure, especially if multiple contactors are ganged. ## Mechanical endurance and operating rate That rate is the mechanical limit — actual electrical life depends on the load switched (AC-1, AC-3, etc.) and will typically be lower for motor loads. ## Suppressor note — external diode required This coil ships without a built-in suppressor module. For DC control circuits, a free-wheeling diode must be added across the coil terminals to prevent voltage spikes when de-energizing. Without it, the inductive kick can damage PLC outputs or relay contacts driving the coil. Schneider offers a range of add-on suppressor modules (e.g., the LA4 series) that clip onto the contactor base.","metaTitle":"Schneider LX9FK914 TeSys F Contactor Coil, 28-31 V DC","metaDescription":"Active-production specific contactor coil for TeSys F contactors. 28-31 V DC low-consumption, 550 VA inrush, 31 VA hold. 60 ms open / 50 ms close.
