It is a DC wide-range coil, meaning it operates across a band of control voltages rather than a single nominal value. The coil's operating time is 30 to 40 ms for closing and 30 to 50 ms for opening, which is typical for a contactor of this frame size and governs how quickly the main power contacts make or break the load circuit. At 68 °F (20 °C), the inrush resistance is 1.25 Ω, dropping to 274.7 Ω in the holding state once the armature seals — the high holding resistance keeps power dissipation low during continuous operation. ## Control voltage and fit notes The coil is rated for 30 V DC nominal control voltage, with an operational range of 0.85 to 1.1 times Uc (25.5 to 33 V DC) at 131 °F (55 °C). Dropout occurs between 0.15 and 0.2 Uc (4.5 to 6 V DC) at the same temperature. It ships without a built-in suppressor module, so if the contactor is switched by a PLC output or solid-state relay, an external flyback diode or varistor should be added across the coil terminals to protect the control circuit from the inductive kick.","metaTitle":"Schneider LX4FG030 TeSys Contactor Coil, 30 V DC, Obsolete","metaDescription":"Schneider Electric LX4FG030 TeSys contactor coil, 30 V DC, obsolete.
