It operates on a 63...70 V DC control circuit and is classified as low consumption. The coil draws an inrush power of 550 VA at 68 °F (20 °C) and a hold-in power consumption of 31 VA at the same temperature, with heat dissipation in the 15...18.3 W range during steady-state operation. This coil is supplied without a built-in suppressor module, so you will need to add external suppression if the control circuit demands it — standard practice for DC coils driving inductive loads. ## Switching performance and durability Opening time is 60 ms; closing time is 50 ms. These figures matter when sequencing contactors in a motor start circuit — the 10 ms asymmetry is typical for DC coils and must be accounted for in interlock timing. For high-duty applications like conveyor indexing or compressor cycling, this rate sets the practical switching ceiling. The ambient air temperature range for operation is 23 to 131 °F (-5 to 55 °C). The control voltage limits are 0.85...1.1 Uc for operational range and dropout at 0.3...0.5 Uc, both at 131 °F (55 °C). The active status removes the urgency of a last-time-buy window, but given its role as a specific contactor coil for the TeSys F platform, verifying compatibility with the specific contactor frame (LX9F body) is the only integration check needed.","metaTitle":"Schneider TeSys LX9FK921 Contactor Coil 63-70 VDC","metaDescription":"LX9FK921 specific contactor coil for TeSys F contactors. 63-70 V DC control voltage, 550 VA inrush, 31 VA hold.
