Fluidra - Pool Pump Motor Run Capacitor 12 µF / 450 V

Fluidra – Pool Pump Motor Run Capacitor 12 µF / 450 V

This is a genuine Fluidra OEM run capacitor rated at 12 microfarads and 450 volts, designed for use in single-phase pool pump motors. It maintains the phase shift in the motor’s run winding during normal operation, keeping the pump running smoothly and efficiently. Replacing a failed or degraded capacitor restores full motor performance and prevents overheating or burnout.

How It Works

Run capacitors remain active throughout the entire operating cycle of a single-phase motor, unlike start capacitors which are only engaged briefly at startup. By maintaining a precise electrical phase difference between the motor windings, the capacitor ensures consistent torque, quiet operation, and energy-efficient running. A pump that hums but struggles to run, or draws excess current, is a classic sign of a failing run capacitor.

Compatibility

This capacitor is a genuine Fluidra spare part intended for compatible Fluidra single-phase pool pump motors that specify a 12 µF run capacitor. Always verify the capacitance value (µF) marked on your original capacitor before ordering — the µF rating must match exactly. The 450 V voltage rating provides a safe margin for standard 230 V single-phase mains supplies used across Europe.

Installation

Capacitor replacement should be carried out by a qualified electrician or pool technician, as capacitors can store a dangerous electrical charge even when the pump is unplugged. Always discharge the old capacitor safely before handling. Ensure the replacement is securely mounted and all connections are tight and insulated before restoring power.
