The WB1GA024 is a low-consumption contactor coil from the TeSys range, wound for 24 V AC at 50 Hz. It is the replacement coil for CV1B and CV3B contactors — if you have one of those bodies on the bench, this is the coil that mates to it. The inrush draw is 130...160 W (345...415 VA at 50 Hz, 0.38 power factor), settling to a hold-in consumption of 16...25 W (45...65 VA at 50 Hz, 0.35 power factor). The closed-circuit inductance is 0.026 H, and the average coil resistance is 0.4 Ω — all measured at 68 °F (20 °C). Control voltage limits are 0.85...1.1 Uc at 50 Hz, up to 131 °F (55 °C). Mechanical durability is rated at 1,200,000 cycles.
Sourcing runs through the surplus and broker channel. We can locate WB1GA024 units against an RFQ — think landed, not list, since the paperwork and traceability for an obsolete part need to be clean before it hits your BOM line.
