The WB1JB433 is a replacement coil from the Schneider Electric TeSys range, designed specifically for CV1B and CV3B contactors. It is an AC/DC-operated, low-consumption coil with a 240 V DC control circuit voltage.
Key Ratings for Fit Verification
The coil draws 130...220 W inrush at 68 °F (20 °C) and settles to a hold-in consumption of 0.4...0.765 W at the same temperature. The 240 V DC control voltage is the only rated control voltage — verify your panel's control supply matches this before specifying.
