It draws 90 to 110 W inrush power (220 to 270 VA at 0.4 power factor) and settles to 13 to 19 W holding power (35 to 55 VA at 0.35 power factor), all measured at 68 °F (20 °C). The coil's closed-circuit inductance is 20 H, with an average resistance of 347 ohms at 68 °F. This part is officially obsolete per the manufacturer's lifecycle status. ## Control circuit voltage limits The coil operates reliably between 0.85 and 1.1 times the rated control voltage (Uc) at 50 Hz, up to 131 °F (55 °C) ambient.","metaTitle":"Schneider TeSys WB1EA550 Contactor Coil, 550 V AC, Obsolete","metaDescription":"Obsolete Schneider TeSys WB1EA550 contactor coil, 550 V AC 50 Hz, for CV1B/CV3B contactors.
