It is a low-consumption coil — draws 550 VA inrush at 20 °C, then settles to 31 VA hold-in power — so the control transformer and wiring can be sized for the peak, not the steady-state. Opening time is 60 ms, closing 50 ms, which is typical for a DC-operated coil of this frame size. The coil has no built-in suppressor module, so an external flyback diode or RC snubber must be added across the coil terminals when driven by a PLC or solid-state output — otherwise the inductive kick can damage the driver. The control circuit voltage is 321-352 V DC. Operational limits are 0.85 to 1.1 Uc at 55 °C; drop-out occurs between 0.3 and 0.5 Uc. The maximum operating rate is 3600 cycles per hour at 70 °C — that is one cycle per second, which is fast for a DC coil; verify the contactor's own mechanical limit if cycling at that rate.","metaTitle":"TeSys LX9FK935 specific contactor coil, 321-352 V DC, obsole","metaDescription":"Obsolete TeSys F specific contactor coil, 321-352 V DC low consumption. 550 VA inrush, 31 VA hold-in, 10 Mcycles mechanical.
