It's the part that pulls the contactor in — no coil, no switching. Rated for a 56 V AC 50 Hz control circuit, this coil draws 75 VA inrush at 0.55 power factor and settles to 8 VA sealed at 0.28 power factor. That inrush-to-sealed ratio is typical for AC-operated contactor coils — the high inrush pulls the armature in, then the sealed VA holds it closed with less heat. Coil resistance measures 28.09 Ohm at 20 °C, ±10 %, with an inductance of 0.95 mH. These values matter for troubleshooting — an open coil or a shorted turn shows up as a resistance reading outside that band. Classified under 18402-WORLD SERVICE PARTS(CONTROL ACCESS), meaning it's stocked as a serviceable spare, not a design-in component for new panels. That's fine for a replacement coil — you're swapping it into an existing TeSys contactor, not specifying it for a greenfield build. This coil mounts directly onto the TeSys contactor magnet assembly — no adapter, no bracket. The LX1 coil family shares the same mechanical footprint across the D-range contactors, so fit is consistent if you're replacing a failed coil on an LC1D or LC1F frame. Wire the 56 V AC supply to the coil terminals with proper polarity for the AC circuit — AC coils aren't polarity-sensitive, but the suppression network (if fitted) may be. Verify the control transformer is sized for the 75 VA inrush; a marginal transformer can cause the contactor to chatter on pull-in.","metaTitle":"Schneider LX1LB056 TeSys Coil, 56 V AC 50 Hz, Active","metaDescription":"Schneider Electric LX1LB056 TeSys replacement coil, 56 V AC 50 Hz control voltage, 28.09 Ohm resistance, 75 VA inrush / 8 VA sealed.
