The Schneider Electric WB1EA655 is a low-consumption contactor coil from the TeSys range, designed specifically for CV1B and CV3B contactors. It accepts AC or DC control voltage, making it a direct replacement coil in those contactor frames.
The low-consumption coil type means it draws less inrush and hold current than standard coils, which matters when the control transformer or PLC output card has limited current budget. The AC/DC control circuit type gives flexibility — same coil works on 24 VAC or 24 VDC control supplies, simplifying panel wiring and reducing spare coil variants needed on site.
