The WB1GA905 is a replacement coil from the Schneider TeSys range, designed for the CV1B and CV3B contactor frames. It accepts both AC and DC control voltage, so it can drop into a panel regardless of whether the control transformer is feeding the contactor or a 24 VDC PLC output is switching it.
Sourcing posture
Because the WB1GA905 is obsolete, it is sourced strictly on a quoted-to-order basis through our surplus and broker network. We do not carry it on the shelf. Send an RFQ with your quantity and target delivery window — we will check our multi-source channel for NOS or verified pulls. No official replacement exists from Schneider for this specific coil, so the BOM line either commits to the surplus market or redesigns around a current-production contactor and its matching coil.
