It is the replaceable coil assembly for TeSys F contactors that require a 19...21 V DC control voltage. The coil uses low-consumption AC 40...400 Hz and DC technology, meaning it draws less steady-state current than a standard coil once the contactor is sealed. Rated control circuit voltage is 19...21 V DC. The operational limits span 0.85...1.1 Uc at 55 °C, so the coil must see at least about 16 V to pick reliably and can tolerate up to about 23 V. Drop-out occurs between 0.3...0.5 Uc, which means the contactor drops out cleanly between roughly 5.7 and 9.5 V — a wide hysteresis that prevents chatter on a sagging supply. Opening time is 60 ms, closing time 20 ms. That 3:1 ratio is typical for DC-operated contactor coils — the slower drop-out is inherent to the magnetic circuit decay. For applications where fast arc extinction matters (motor starting, capacitor switching), verify that 60 ms opening meets your coordination requirements. ## Power draw and thermal management Inrush power hits 733 W at 20 °C — that's the peak to overcome the air gap and seat the armature. Once sealed, hold-in power drops to 48 W at the same temperature. The difference between inrush and hold-in is what the low-consumption design achieves: the coil driver reduces current after pick-up, so the panel sees a fraction of the thermal load during continuous operation. Steady-state heat dissipation runs 22.8...27.8 W. That's the heat the coil dumps into the enclosure. In a densely packed panel, that 5 W spread matters for internal temperature rise — account for it in your thermal budget, especially if the contactor cycles near its maximum operating rate of 1800 cycles per hour at 70 °C. Mechanical durability is rated at 5 million cycles. That's the mechanical life of the coil assembly itself, not the contactor's electrical endurance under load. In a high-cycle application (sorting conveyor, press control), the coil will outlast the main contacts on heavy inductive loads. ## Installation note — no built-in suppressor The coil comes without a built-in suppressor module. That means you must add an external flyback diode or RC snubber across the coil terminals if the control circuit drives it from a PLC output or relay. Without suppression, the inductive kick from the coil can reach several hundred volts — enough to damage solid-state outputs or cause EMI issues on nearby sensors. A standard 1N4007 diode (cathode to positive) across the coil handles DC suppression cleanly. ## Where it goes and what it tolerates The coil is a DIN-rail-mounted accessory that snaps onto the TeSys F contactor body — no separate panel space required beyond the contactor footprint.","metaTitle":"Schneider LX9FL910 TeSys F Contactor Coil, 19..21 V DC","metaDescription":"Active TeSys F specific contactor coil, 19..21 V DC low consumption. 48 W hold-in, 733 W inrush. 60 ms open, 20 ms close.
