Davey - ProMatic MPS36 / MPS50 Control Unit Fuse 5A - M2906

Davey – ProMatic MPS36 / MPS50 Control Unit Fuse 5A

This is the genuine Davey 5-ampere replacement fuse (part M2906) for the ProMatic MPS36 and MPS50 salt water chlorinator control units, including ESR and ESC controller variants. It protects the power supply and control electronics from overcurrent, and is the first component to inspect when the unit stops operating or trips unexpectedly.

Compatibility

This fuse is specifically rated and approved for the ProMatic MPS36 and MPS50 (and their ESR/ESC equivalents). It is not interchangeable with the 3A fuse used in the smaller MPS16 and MPS24 models — always confirm your model before ordering. One fuse is supplied per unit.

Why genuine matters

Using the correct OEM-specified 5A rating ensures the control board is protected within Davey’s designed tolerances. An incorrectly rated fuse — whether too low or too high — can cause nuisance tripping, inadequate protection, or permanent damage to the PCB. A genuine Davey part guarantees the right specification every time.

Installation

Fuse replacement should be carried out by a qualified technician with the unit fully isolated from the mains supply. Always investigate the root cause of a blown fuse before fitting the replacement, as a recurring failure may indicate a deeper electrical fault in the cell cord, PCB, or power supply.
