Overview
The LX9FJ931 is a Schneider TeSys F specific contactor coil, designed for 220-230 V AC control circuits at 40-400 Hz with low consumption. It draws 23 W and 500 VA, with a coil resistance of 99.5 ohms and inductance of 5.0 mH. This coil is intended for use with TeSys F LC1F400 contactors and is supplied without a built-in suppressor module.
The LX9FJ931 is a low-consumption AC coil that operates across 40-400 Hz, making it suitable for variable-frequency supplies. Its 23 W power consumption and 11.4-13.9 W heat dissipation keep thermal rise moderate in enclosed panels. With an operating time of 60 ms and a maximum operating rate of 3600 cycles per hour at 70 °C, it supports high-speed switching applications. The coil has no built-in suppressor; external suppression (e.g., RC snubber or varistor) must be added across the coil terminals when driving inductive loads to protect control contacts.
Applications
As a replacement coil for TeSys F contactors, the LX9FJ931 is used in motor control centers, pump panels, conveyor systems, and HVAC equipment where 230 V AC control circuits are standard.
The LX9FJ931 is officially discontinued by Schneider, with a last order date of December 31, 2028. Buyers should plan for last-time buy or identify a suitable replacement coil for new designs. For existing installations, sourcing through surplus or broker channels may be necessary after the discontinuation date. No direct successor part number is listed by Schneider.
