This coil specifically provides the 415...440 V AC 50 Hz control circuit voltage for the starter's magnetic operator. The control voltage limits are documented: operational range is 0.85...1.1 Uc, with dropout between 0.25...0.7 Uc at temperatures below 131 °F (55 °C). Inrush power draws 350...400 VA at 50 Hz (cos φ 0.55), dropping to 20...30 VA hold-in power (cos φ 0.28) once the magnetic circuit closes. Coil resistance measures 116.46 Ohm at 68 °F (20 °C); closed-circuit inductance is 23.7 H. For a BOM freeze or line-down replacement, the procurement path is a one-off search through the independent channel. ## Integration Constraints for the Panel OEM This coil mounts into the TeSys Integral starter base — it is not a standalone contactor coil. The control circuit is AC 50 Hz only; do not apply DC or 60 Hz without verifying the magnetic circuit's impedance curve. The 415...440 V AC range is specific to 400 V line-to-line systems with nominal tolerance; a 480 V supply exceeds the upper limit and risks saturation or thermal damage. Inrush current at 415 V is approximately 0.84 A (350 VA / 415 V), settling to a hold-in current around 48 mA (20 VA / 415 V). The control transformer supplying this coil must be sized for the inrush peak, not the steady-state draw. The dropout voltage range (0.25...0.7 Uc) means the starter drops out between 104 and 308 V — useful for brownout ride-through assessment in the panel design.","metaTitle":"TeSys LX1LD415 Coil, 415-440 VAC 50 Hz, Obsolete","metaDescription":"TeSys LX1LD415 replacement coil for Integral starters, 415-440 VAC 50 Hz.
