Control circuit is AC 40-400 Hz, rated 265-277 V AC. Coil holds in at 0.85-1.1 Uc and drops out between 0.2-0.4 Uc at 131 °F (55 °C). Opening time is 130-230 ms, closing time 40-80 ms — the 40 ms close means it engages quickly for a coil of this class, but the 230 ms open window is wider than a DC coil; factor that into safety-circuit timing if the contactor drives an emergency-stop path. Because it is a current-production part, the buyer can quote against an RFQ for scheduled delivery rather than hunting surplus. No official replacement exists; this is the direct order code for the 265-277 V AC coil. ## Thermal and electrical load Heat dissipation is 44 W at 40-400 Hz — enough that a densely packed panel should account for the thermal load when sizing cabinet ventilation or spacing adjacent components. Inrush power is 2100 VA at cos φ 0.9; hold-in power drops to 50 VA at cos φ 0.3. The inrush surge matters for transformer sizing or shared control-circuit supplies — a 50 VA hold-in is modest, but the 2100 VA peak at pull-in can drop a lightly loaded control transformer. Coil resistance: 29.8 Ω inrush, 1330 Ω holding at 68 °F (20 °C). No built-in suppressor module — if the contactor drives an inductive load, plan external RC snubber or varistor across the coil terminals to limit switching transients. ## Mechanical endurance Rated for 5 million mechanical cycles at a maximum operating rate of 600 cycles per hour at 131 °F (55 °C). That rate is typical for a contactor coil in a cycling application — conveyor indexing or pump sequencing — but sustained operation above 600 cyc/h will shorten life.","metaTitle":"LX1FX280 TeSys F Contactor Coil, 265-277 V AC","metaDescription":"TeSys F contactor coil LX1FX280, 265-277 V AC 40-400 Hz.
