The Schneider Electric TeSys WB1GA550 is a low-consumption contactor coil designed for the CV1B and CV3B contactor frames. It operates on a 550 V AC 50 Hz control circuit, with an operational voltage range of 0.85...1.1 Uc at 50 Hz (at <131 °F (55 °C)). Inrush power draw is 130...160 W (345...415 VA at 50 Hz, power factor 0.38) at 68 °F (20 °C); holding power drops to 16...25 W (45...65 VA at 50 Hz, power factor 0.35). The coil's closed-circuit inductance is 14 H, with an average resistance of 212.39 Ohm at 68 °F (20 °C).
