The Schneider TeSys WB1GA400 is a replacement contactor coil, designed for the CV1B and CV3B contactor frames. It's a low-consumption AC coil rated for 400 V AC at 50 Hz and 440 to 450 V AC at 60 Hz. Control circuit voltage limits are 0.85 to 1.1 Uc at 50 and 60 Hz, up to 55 °C. Inrush power runs 130 to 165 W and 345 to 475 VA depending on frequency and temperature; hold-in drops to 16 to 30 W and 45 to 75 VA. The closed-circuit inductance is 7.3 H, with an average DC resistance of 110.71 ohms at 20 °C.
This part is obsolete per Schneider's lifecycle status.
What to watch when swapping
The coil is AC control circuit only. It's a service part for the CV1B and CV3B contactors. If you're replacing a failed coil on an existing panel, verify the contactor frame matches. If the contactor itself is also obsolete, a complete contactor replacement may be the faster path.
