The Schneider Electric TeSys WB1EA110 is a low-consumption contactor coil rated for 110 V AC at 50 Hz, designed as a direct replacement coil for CV1B and CV3B contactors in the TeSys range. Inrush power draw is 90 to 110 W (or 220 to 270 VA at 0.4 power factor) at 68 °F (20 °C), dropping to a hold-in consumption of 13 to 19 W (35 to 55 VA) once the contactor is sealed — a typical low-burn coil profile that keeps panel heat down. The coil operates reliably within 0.85 to 1.1 times the rated control voltage at 50 Hz, up to 131 °F (55 °C) ambient, with a closed-circuit inductance of 0.8 H and an average resistance of 12.54 ohms at 68 °F (20 °C).
