The WB1EA127 is a replacement coil in the TeSys range, designed for CV1B and CV3B contactors. It operates on a 127 V AC control circuit at 50/60 Hz and is classified as a low-consumption type coil. The inrush power draw sits at 220...270 VA at 50 Hz with a 0.4 power factor, while the sealed hold-in drops to 35...55 VA at 0.35 power factor.
Electrical characteristics for the panel
The coil draws 90...110 W inrush at 68 °F (20 °C), settling to 13...19 W sealed hold-in. Average DC resistance measures 14.83 ohms at the same temperature. The closed-circuit inductance is 1.07 H. Control voltage limits are 0.85...1.1 Uc at 50/60 Hz, up to 131 °F (55 °C) ambient.
