The Schneider Electric TeSys WB1EA315 is a low-consumption contactor coil designed for CV1B and CV3B contactors in the TeSys range. It operates on a 305 V AC control circuit at 50 Hz or 340 V AC at 60 Hz, with an operating time of 9 ms. This is a service part — a replacement coil, not a complete contactor — so the buyer is swapping a failed coil on an existing contactor frame, not selecting a new contactor.
The coil draws 90–110 W inrush at 20 °C (75–95 W on the alternate winding), settling to 13–19 W hold-in power. Inrush VA is 220–270 VA at 50 Hz and 225–275 VA at 60 Hz. The control circuit voltage limits are 0.85–1.1 Uc at 50/60 Hz up to 55 °C. Tightening torque for the coil connections is 30 N·m (265.5 lbf·in).
