The Schneider TeSys WB1GA230 is a low-consumption DC contactor coil designed for the CV1B and CV3B contactor frames. It operates on a 110 V DC control circuit with a nominal coil resistance of 33 Ohm at 68 °F (20 °C). The control voltage limits are 0.85 to 1.1 times Uc at up to 131 °F (55 °C), which defines the hold-in range for reliable operation under temperature.
Mechanical Endurance and Deployment Fit
Rated for 1,200,000 mechanical cycles, this coil is built for moderate-duty switching applications — think conveyor sections, pump starters, or HVAC contactor banks where the cycle rate is not extreme. The low-consumption coil design reduces heat buildup in the panel, which matters when the contactor is packed into a dense DIN-rail enclosure alongside other heat-generating components. The 110 V DC control voltage is common in industrial DC bus systems and battery-backed control schemes, so verify your control transformer or power supply matches that nominal before committing the line.
