Zodiac – Compressor relay (30A) – B0217500A

The Zodiac B0217500A is a genuine OEM replacement compressor relay rated at 30 amperes, designed specifically for use within Zodiac pool heating systems. The relay acts as an electrically operated switch that controls the power supply to the compressor unit inside a heat pump or similar pool heating appliance. When the control board sends a signal, the relay engages or disengages the compressor circuit, enabling precise and safe management of the heating cycle. Without a functioning relay, the compressor cannot start or stop correctly, leading to heating failures or potentially unsafe operating conditions.

As a direct replacement part sourced from Zodiac’s authorised components catalogue, this relay ensures full compatibility and reliable performance within the supported equipment range. Relays of this type are high-current switching components; the 30A rating means this relay is built to handle the substantial inrush and running current demands of a refrigeration-cycle compressor. Using a correctly rated OEM relay is critical — an undersized relay will fail prematurely or create a fire risk, while a non-genuine alternative may not meet the precise electrical or dimensional requirements of the original assembly.

Technical characteristics and installation context

The B0217500A relay is engineered to the electrical specifications required by the Zodiac heat pump platform. Its 30A current rating provides adequate headroom for compressor start-up surges, which are typically significantly higher than steady-state running current. The component is designed to be installed on the internal control board or relay mounting bracket within the heat pump cabinet, replacing a failed or suspect relay during servicing. Installation should be carried out by a qualified technician familiar with pool heating equipment and electrical safety procedures. Always isolate the appliance from the mains supply before commencing any internal component replacement.

This part appears in the official Zodiac 2018 and 2020 spare parts catalogues, confirming its continued availability as a listed service component for compatible Zodiac heat pump models. Cross-reference the SKU B0217500A against your specific heat pump model’s spare parts diagram to confirm fitment before ordering.

Suitability and application

This relay is intended for pool owners, service engineers, and pool equipment specialists who are servicing or repairing a Zodiac heat pump unit where the compressor relay has failed. It is suited to installations across both residential and light commercial pool contexts where Zodiac heat pump technology is deployed. If you are experiencing a fault where the compressor does not activate, runs continuously, or the heat pump displays a compressor-related error code, a faulty relay is a common cause and this part provides the correct OEM solution. Always verify your heat pump model number and consult the official Zodiac spare parts catalogue or a Zodiac-authorised service centre to confirm compatibility with your specific unit before installation.
