Fluidra - Replacement Slow-Blow Fuse T500mA 5×20mm for KIT4SAL DOMS2 Salt Chlorinator

Fluidra – Replacement Slow-Blow Fuse T500mA 5×20mm for KIT4SAL DOMS2 Salt Chlorinator

This is the genuine Fluidra replacement slow-blow (time-delay) glass cartridge fuse rated at 500mA and 250V, in the standard 5×20mm format. It is a critical protection component inside the KIT4SAL DOMS2 salt chlorinator control unit, designed to safeguard the electronics against overcurrent events without nuisance tripping during normal operation.

Compatibility

This fuse is the factory-specified spare part for the Idegis KIT4SAL DOMS2 salt electrolysis control kit — a professional-grade multi-output chlorinator controller used in residential and semi-commercial pool installations across Europe. Always verify your existing fuse rating and physical dimensions before ordering to ensure a correct match.

Why Genuine Matters

Using a genuine Fluidra fuse ensures the correct slow-blow characteristic, voltage rating, and breaking capacity are maintained. An incorrect fuse can either fail to protect the controller board from damaging surges, or blow prematurely under the normal inrush currents associated with salt electrolysis equipment. A like-for-like genuine replacement keeps your warranty intact and your chlorinator operating safely.

Installation

Fuse replacement should be carried out by a qualified technician with the unit fully disconnected from the mains supply. Always identify and resolve the root cause of a blown fuse before fitting the replacement. Refer to your KIT4SAL DOMS2 documentation for the exact fuse location within the control unit.
