The Schneider Electric WB1EA264 is a low-consumption contactor coil from the TeSys range, designed specifically for CV1B and CV3B contactors. It operates on a 240 V AC control circuit at 50 Hz or 260 V AC at 60 Hz, with operational limits of 0.85 to 1.1 times Uc at up to 55°C. This is a service part for existing TeSys installations, not a new-design component.
This part is officially obsolete. It was a service spare for legacy CV1B and CV3B contactor lines, and the manufacturer no longer produces it. For a BOM line requiring WB1EA264, the only sourcing channel is the independent surplus and broker market. If you are holding a critical spare for an aging TeSys panel, this is the kind of part you buy the moment you see it — one in the cabinet before it fails.
The 9 ms operating time is the pull-in speed for the contactor armature — fast enough for standard motor starting and general switching, but not a high-speed transfer application. The inrush power draw is 90 to 110 W at 20°C, settling to a hold-in consumption of 13 to 19 W. This low-consumption coil design reduces thermal stress on the contactor and panel wiring compared to older continuous-duty coils. The inrush VA is 220 to 270 VA at 50 Hz and 225 to 275 VA at 60 Hz, which matters when sizing the control transformer for a panel with multiple contactors pulling in simultaneously.
