It operates on a 250-283 V DC control circuit and is classified as low consumption, drawing 550 VA inrush and 31 VA hold-in power at 20 °C. The coil has a mechanical durability of 10 million cycles and a maximum operating rate of 3600 cycles per hour at 70 °C. Opening time is 60 ms, closing time is 50 ms. The coil dissipates 15-18.3 W of heat, which should be factored into panel thermal calculations if a replacement or equivalent is being sourced. The control circuit accepts AC 40-400 Hz or DC low-consumption drive, but this specific variant is DC-only at 250-283 V. ## Integration notes The coil comes without a built-in suppressor module, so an external RC snubber or free-wheeling diode must be added across the coil terminals if driving from a PLC output or solid-state relay — otherwise the inductive kickback can damage the control circuit. Operational voltage limits are 0.85-1.1 Uc at 55 °C, with dropout at 0.3-0.5 Uc. These define the real-world hold-in and dropout margins for a panel environment.","metaTitle":"Schneider Electric LX9FK933 TeSys F Contactor Coil, 250-283","metaDescription":"Schneider Electric LX9FK933 specific contactor coil for TeSys F contactors. 250-283 VDC control circuit, low consumption.
