It draws 350...400 VA inrush at 50 Hz with a 0.55 power factor, then settles to 20...30 VA hold-in at 0.28 power factor — a typical AC magnet coil profile that means the control transformer must be sized for the inrush peak, not the sealed draw. ## Control circuit voltage limits The coil operates across 0.85...1.1 Uc (382.5...495 V AC) and drops out between 0.25...0.7 Uc (112.5...315 V AC) at up to 55 °C. That dropout band is wide — expect release somewhere in that range depending on temperature and coil history, so verify the control scheme's undervoltage release threshold if the application relies on a precise dropout point. ## Category and range context Listed under category 18402 — WORLD SERVICE PARTS (CONTROL ACCESS) — and part of the TeSys range, this coil is a service-part replacement for Integral-series contactors and starters already in the field. It is not a design-in component; its role is to keep existing panels running.","metaTitle":"TeSys LX1LD450 coil, 450 V AC 50 Hz, obsolete","metaDescription":"TeSys LX1LD450 replacement coil for Integral contactors, 450 V AC 50 Hz control circuit.
