Zodiac - ZS500 filter inductor 30KHz 1.5mH 22A - B0050700A

Zodiac – ZS500 filter inductor 30KHz 1.5mH 22A – B0050700A

The Zodiac B0050700A is an OEM replacement filter inductor designed specifically for the Zodiac ZS500 heat pump range. This inductor is a key internal electrical component responsible for smoothing and filtering the high-frequency switching signals generated by the inverter drive circuit within the heat pump. Operating at a switching frequency of 30KHz with an inductance of 1.5mH and a rated current of 22A, it ensures stable, efficient power delivery to the compressor and associated drive electronics, reducing electromagnetic interference and protecting sensitive components from voltage spikes and harmonic distortion.

Inductors of this type are critical in inverter-based pool heat pumps, where variable-speed compressors rely on clean, regulated power waveforms to operate reliably across a wide range of conditions. A failing or damaged inductor can manifest as erratic heat pump behaviour, error codes, or complete shutdown of the unit. Replacing it with the correct OEM part ensures the ZS500 returns to its original performance specification.

Technical characteristics and compatibility

This filter inductor is rated at a switching frequency of 30KHz, an inductance value of 1.5mH, and a continuous current rating of 22A. These values are precisely matched to the internal inverter architecture of the Zodiac ZS500 heat pump. The component is engineered to handle the thermal and electrical demands of continuous pool heating operation, and its specifications must be matched exactly when replacing — substituting an inductor with different inductance or current ratings risks damaging the inverter board or compressor drive circuit.

The Zodiac ZS500 is a high-efficiency inverter pool heat pump designed for residential swimming pools. Spare parts such as this inductor are intended for installation by qualified service technicians, as work involves access to live high-voltage electrical components inside the heat pump cabinet. The part is sourced directly from Zodiac (Fluidra) and is guaranteed to meet the original manufacturing specification.

Suitability and application

This replacement filter inductor is intended exclusively for Zodiac ZS500 series pool heat pumps. It is not a universal component and must only be fitted to the specific model for which it is designed. It is suitable for residential pool installations where the ZS500 heat pump is used as the primary pool water heating source. This part is recommended when the existing inductor shows signs of physical damage, overheating, or when diagnostic testing confirms it is outside specification. Always consult the Zodiac ZS500 service documentation or a qualified pool technician before undertaking replacement of internal electrical components.
