It operates on a control circuit voltage of 89...99 V DC, with low-consumption coil technology that draws 550 VA inrush and 31 VA hold-in at 68 °F (20 °C). Switching times are 60 ms opening and 50 ms closing, with a maximum operating rate of 3600 cycles per hour at 158 °F (70 °C). ## Sourcing Reality: Obsolete, Sourced to Order If you are maintaining a TeSys F contactor in service, the procurement path is a last-time-buy or surplus/broker channel. Quote to order. The 89...99 V DC control voltage range is tight — operational limits are 0.85 to 1.1 Uc at 131 °F (55 °C), meaning the coil holds in reliably between about 76 V and 109 V DC. Drop-out occurs between 0.3 and 0.5 Uc, so the contactor drops out cleanly below about 27 V DC. If your control supply sags outside these bands, the coil may not hold or may chatter. Heat dissipation of 15...18.3 W means the coil generates noticeable heat inside the enclosure. In a densely packed panel with multiple TeSys F contactors running continuously, factor this into your thermal budget — especially if ambient temperature approaches the upper operating limit of 131 °F (55 °C). The coil ships without a built-in suppressor module. If your control circuit requires flyback suppression (common with PLC or solid-state outputs driving the coil), you will need to add an external diode or RC snubber across the coil terminals. This is standard practice for DC-operated contactor coils.","metaTitle":"TeSys LX9FK924 Specific Contactor Coil, 89-99 V DC, Obsolete","metaDescription":"TeSys LX9FK924 specific contactor coil for TeSys F contactors, 89-99 V DC low consumption.
