Zodiac - Compressor capacitor Toshiba 9 KW 50µF - B0049700A

Zodiac – Compressor capacitor Toshiba 9 KW 50µF – B0049700A

The Zodiac B0049700A is an original replacement compressor capacitor designed for use with Toshiba compressor units rated at 9 kW, featuring a capacitance value of 50µF. The run capacitor plays a critical role in the operation of a heat pump compressor: it stores and releases electrical energy to maintain a consistent phase shift in the motor winding, ensuring smooth and efficient motor startup and continuous running. Without a functioning capacitor, the compressor motor may fail to start, run erratically, or draw excessive current, leading to overheating or permanent motor damage.

As a genuine Zodiac spare part, this capacitor is manufactured to the original equipment specification, ensuring dimensional and electrical compatibility with the Toshiba compressor assemblies used in Zodiac residential pool heat pumps. Using an OEM-matched capacitor rather than a generic substitute helps preserve the electrical integrity of the compressor circuit and supports the long-term reliability of the heat pump system.

Technical characteristics and compatibility

This capacitor carries a rated capacitance of 50µF, which is the correct specification for the 9 kW Toshiba compressor variants fitted in certain Zodiac residential heat pump models. Capacitance tolerance and voltage rating are matched to the original component, meaning the motor winding receives the correct phase displacement current during every start and run cycle. The unit is a direct plug-and-play replacement, designed to fit the existing capacitor housing and terminal configuration within the heat pump cabinet, minimising installation time for qualified technicians. It is important to ensure the power supply to the heat pump is fully isolated before replacing any capacitor, as capacitors can retain a charge even after power is disconnected.

Cross-referencing across multiple Zodiac catalogues confirms that SKU B0049700A is consistently listed as the compressor capacitor for the Toshiba 9 kW / 50µF specification, making it straightforward to identify as the correct part when servicing compatible Zodiac heat pump units.

Suitability and application

This part is intended for pool owners, pool service professionals, and technicians carrying out maintenance or repair on Zodiac residential pool heat pumps equipped with a Toshiba 9 kW compressor. It is a specialist electrical component and should only be installed by a qualified technician familiar with heat pump servicing procedures. If your Zodiac heat pump is displaying symptoms such as failure to start, compressor clicking without running, or tripping the circuit breaker, a faulty run capacitor is a common cause, and replacing it with this genuine Zodiac part is the recommended first step in diagnosis and repair. Always verify the capacitance rating of the original component before ordering to confirm suitability for your specific heat pump model.
