The Schneider TeSys WB1HA160 is a low-consumption contactor coil designed for the CV1B and CV3B contactor frames. It operates on a control circuit voltage of 150 V AC at 50 Hz or 175 V AC at 60 Hz, with operational limits of 0.85...1.1 Uc at those frequencies up to 55 °C.
The inrush power draw is 150...280 W at 20 °C, with an apparent power of 180...340 VA at 50 Hz. The average coil resistance is 10.24 Ω at 20 °C. These numbers matter for sizing the control transformer and ensuring the coil's thermal rise stays within the contactor's enclosure limits — the low-consumption design helps keep heat down in a crowded panel.
