It is the replacement coil for TeSys D, K, and F contactor frames, meaning it directly swaps into those contactor assemblies to restore or configure the control voltage. The coil operates with an opening time of 100 to 170 ms and a closing time of 40 to 75 ms, and it is rated for 10 million mechanical cycles at a maximum operating rate of 2400 cycles per hour at 131 °F (55 °C). It has no built-in suppressor module, so an external RC snubber or varistor must be added across the coil terminals if the application requires EMI suppression or protection for the control circuit contacts. The coil resistance is 548 ohms inrush and 13341 ohms holding at 68 °F (20 °C). The high holding resistance means low power dissipation once the contactor is sealed, but the inrush current is substantial — ensure the control transformer and wiring can handle the momentary draw. The control voltage limits are 0.85 to 1.1 Uc for operation and 0.3 to 0.5 Uc for drop-out at 131 °F (55 °C). ## Deployment Context This coil mounts directly onto TeSys D, K, or F contactor frames — no additional hardware needed. The contactor itself is typically DIN-rail or panel-mounted inside a control enclosure, switching motor loads, resistive heaters, or other industrial loads. The ambient operating temperature range is 23 to 131 °F (-5 to 55 °C), suitable for most indoor industrial environments without derating.","metaTitle":"Schneider LX1FK910 TeSys Contactor Coil, 910 V AC, Obsolete","metaDescription":"Schneider TeSys LX1FK910 contactor coil, 910 V AC 50/60 Hz, obsolete.
