The Schneider Electric WB1GA440 is a low-consumption contactor coil from the TeSys range, designed specifically for CV1B and CV3B contactors. It operates on a 440 V AC control circuit at 50 Hz or 500 V AC at 60 Hz. This coil pulls in with an inrush power of 130 to 160 W at 20 °C (130 to 165 W on some conditions), drawing 345 to 415 VA at 50 Hz or 370 to 475 VA at 60 Hz. Once sealed, hold-in power drops to 16 to 25 W (45 to 65 VA at 50 Hz, 50 to 75 VA at 60 Hz). The average DC resistance across the winding is 123.32 Ω at 20 °C, with a closed-circuit inductance of 8.9 H. The control voltage limits are 0.85 to 1.1 times Uc at both 50 and 60 Hz, valid up to an ambient temperature of 55 °C. This means the coil reliably picks up and holds across a 374 to 484 V range at 50 Hz, and 425 to 550 V at 60 Hz.
