Swimming Pool Circulation Pump VFD Wiring Diagram

Materials

About this detail

Power is supplied from a 460-volt, 3-phase, 60-hertz main circuit breaker feeding a line reactor connected to an adjustable frequency drive. A bypass contactor and line contactor provide alternative circuit paths around the drive unit. Control inputs receive signals from a BECSys controller with a 120-volt pump run output and an off-bypass switch. Output lines drive the 25-horsepower swimming pool circulation pump rated at 34.0 full load amps through an overload protection device, while indicator lights display auto, run, fault, power-on, and contactor status.
