The WB1HA048 is a low-consumption contactor coil from the Schneider TeSys range, designed to operate the CV1B and CV3B contactors. It is rated for 48 V AC at 50 Hz control voltage, with an operational voltage tolerance of 0.85 to 1.1 Uc at 50 Hz up to 55 °C. At 20 °C, the coil draws an inrush power of 155 to 190 W (500 to 615 VA at 50 Hz, power factor 0.31) and a hold-in power of 22 to 35 W (60 to 85 VA at 50 Hz, power factor 0.38). The average resistance is 0.94 ohm, and the inductance of the closed circuit is 0.085 H.
