It operates on a 55 V AC control circuit at 40...400 Hz, with low-consumption coil technology — meaning it draws 950...1180 VA inrush and settles to 8.9...10.9 VA holding at 68 °F (20 °C). The coil dissipates 8...9.8 W of heat during continuous operation, which matters for enclosure thermal budgeting when replacing a failed coil in a panel. Control circuit voltage limits are specified at 0.85...1.1 Uc for operational hold-in at 131 °F (55 °C), and drop-out occurs between 0.35...0.55 Uc at the same temperature. This means the coil reliably picks up when line voltage stays above 46.75 V AC and drops out cleanly below 19.25 to 30.25 V AC — important for brownout ride-through assessment on the control transformer. Operating time is 130 ms opening and 35 ms closing, which is standard for a contactor coil of this class. Ambient air temperature for operation spans -5...55 °C (23...131 °F), covering most indoor panel environments. The coil has no built-in suppressor module — if your control circuit requires flyback suppression (for PLC output or relay drive), you will need to add an external RC snubber or varistor across the coil terminals.","metaTitle":"TeSys LX9FG055 specific contactor coil, 55 V AC, obsolete","metaDescription":"TeSys F specific contactor coil, 55 V AC 40..400 Hz low consumption.
