It is the component that energizes the contactor armature — without it, the main power poles do not close. The closing time of 40 to 50 ms and opening time of 40 to 65 ms define the mechanical response window for the contactor it drives. The coil draws 750 W inrush at 20 °C, then holds at 5 W once the armature seats. The inrush resistance is 11 Ω, rising to 2120 Ω in the holding state. The inductance of the closed circuit is 287 H, which governs the L/R time constant for suppression circuit selection — critical when adding a free-wheeling diode or varistor across the coil terminals. The ambient temperature range spans -55 °C to +70 °C, covering most industrial enclosure environments. The coil has no built-in suppressor module, so external transient suppression must be added by the panel builder. Because this is a service part for an installed base of TeSys F contactors, the procurement decision hinges on whether the contactor frame itself is still in service. If the contactor is also being replaced, a complete contactor assembly with an integrated coil may be a more reliable path than sourcing an obsolete coil through secondary markets. ## Control voltage and operating limits The control circuit voltage is 110 V DC, with a wide-range operational band of 0.7 to 1.25 times Uc (77 V to 137.5 V DC at 70 °C). Drop-out occurs between 0.2 and 0.45 Uc (22 V to 49.5 V DC). This wide dropout margin means the coil releases reliably even with significant voltage sag on the DC bus — useful in installations with long control wiring or shared DC supplies.","metaTitle":"TeSys LX4FH090 Contactor Coil, 110 V DC, Obsolete","metaDescription":"TeSys F LX4FH090 contactor coil, 110 V DC wide range, 40-50 ms closing.
