It is the replacement coil for TeSys CV1B and CV3B contactors, meaning if you have one of those contactors with a burned-out or missing coil, this is the part that bolts in. ## Lifecycle reality — obsolete, but sourceable The official product status is obsolete, so treat this as a last-time-buy or surplus-only part. ## What you need to know for sourcing This coil is part of the TeSys range, Schneider's long-running contactor and motor-starter family. It is a low-consumption design, so it draws less holding current than standard coils — useful if your control transformer is marginal or you are running a long control loop with voltage drop. The control circuit accepts both AC and DC, which simplifies stocking: one coil covers both supply types. It comes packaged as a single unit, so order one per contactor you need to repair.","metaTitle":"Schneider WB1EA720 TeSys Contactor Coil, AC/DC for CV1B/CV3B","metaDescription":"Obsolete Schneider TeSys WB1EA720 low-consumption contactor coil, AC/DC control for CV1B/CV3B contactors.
