It is a replacement coil for the LX1D8 series contactors, not a standalone contactor itself. This coil uses AC 50 Hz control technology without a built-in suppressor module, meaning an external RC snubber or varistor is required across the coil terminals if driving it from a PLC output or solid-state relay that needs protection from back-EMF. Rated for a 115 A contactor, this coil pulls 300 VA inrush at 50 Hz cos phi 0.8, dropping to 22 VA hold-in at cos phi 0.3. The 3 to 8 W heat dissipation at 50 Hz means the panel enclosure needs some airflow if multiple coils are ganged together. The coil's average resistance is 441.56 Ohm at 68 °F (20 °C), and its closed-circuit inductance is 30.34 H. These values matter when sizing the external suppression network — a standard RC snubber (e.g., 100 Ω + 0.1 µF) across the coil terminals will limit voltage spikes without slowing dropout beyond the contactor's specification. Control circuit voltage limits are 0.85 to 1.1 Uc for pickup and 0.3 to 0.6 Uc for dropout at 50 Hz and below 131 °F (55 °C). On a 440 V line, that means pickup is guaranteed between 374 V and 484 V, and dropout occurs between 132 V and 264 V — wide enough to ride through moderate sags but not brownout conditions.","metaTitle":"Schneider Electric LX1D8R5 TeSys Contactor Coil, 440 V AC 50","metaDescription":"Schneider Electric LX1D8R5 TeSys contactor coil for 115 A contactor. 440 V AC 50 Hz control circuit.

A parametric match would require a 440 V AC 50 Hz coil for a 115 A TeSys Deca contactor with the same mounting footprint, but without a published cross-reference from Schneider, any substitution must be verified against the contactor's coil terminal layout and mechanical interface."},{"question":"What coil technology does the LX1D8R5 use?","answer":"It uses AC 50 Hz coil technology without a built-in suppressor module.
