Fluidra - 18A Contactor for Power First Premium Heat Pump

Fluidra – 18A Contactor for Power First Premium Heat Pump

This is the genuine Fluidra replacement 18 A contactor designed for the Power First Premium (PF PREM) series of pool heat pumps, including models covered by the Z300 TD8 assembly. The contactor is an electromechanical switching device that controls the main electrical circuits within the heat pump — most commonly the compressor circuit — by opening and closing contacts under load. Replacing a worn or faulty contactor restores reliable start-up and safe operation of the unit.

Compatibility

This contactor is a direct factory replacement part for Fluidra Power First Premium heat pumps, referenced under the Z300 and Power First spare parts catalogues. Always verify your heat pump’s model and serial number against the Fluidra parts diagram before ordering to ensure correct fitment, as multiple contactor ratings may be used across the range.

Why Genuine Matters

Using a genuine Fluidra contactor ensures the part meets the original electrical specifications — rated contact capacity, coil voltage, and mechanical endurance — matched exactly to your heat pump’s control board and wiring. Aftermarket alternatives may differ in coil voltage or terminal layout, risking damage to the control electronics or voiding your warranty.

Installation

Contactor replacement involves working inside the heat pump’s electrical enclosure. All mains power must be fully isolated before beginning work. The job requires correct torquing of power terminals and verification of coil wiring polarity. Installation by a qualified electrician or certified pool heat pump technician is strongly recommended.
