Davey - ProMatic Salt Chlorinator Controller Fuse 3A (MPS16 / MPS24) - M2901

Davey – ProMatic Salt Chlorinator Controller Fuse 3A (MPS16 / MPS24)

This is the genuine Davey 3-ampere replacement fuse for the ProMatic MPS/ESR/ESC series salt water chlorinator control unit. It is a critical electrical protection component inside the controller, protecting the unit’s electronics from overload or short-circuit conditions. Replacing a blown fuse restores power to the controller and gets your chlorination system back up and running quickly.

Compatibility

This 3A fuse fits the Davey ProMatic MPS16 and MPS24 salt water chlorinator controllers, as well as the equivalent ESR and ESC series units sharing the same control platform. It is not intended for larger MPS models such as the MPS36 or MPS50, which require a 5A fuse. Always verify your model before ordering. This part supersedes the former Davey part number 2902.

Why Genuine Matters

Using the correct rated genuine Davey fuse is essential for reliable electrical protection. An incorrect fuse rating can fail to protect the controller’s sensitive electronics, potentially causing costly damage to the power supply board or voiding your warranty. A genuine Davey part ensures exact specification compliance and is covered by Davey’s standard parts guarantee.

Installation

Always isolate mains power to the chlorinator and pump before opening the control unit enclosure. The fuse is typically located on the controller’s circuit board or in a dedicated fuse holder within the housing. If fuses blow repeatedly, this is a sign of an underlying electrical fault — consult a qualified pool technician before replacing the fuse again.
