Fluidra - Slow-Blow Glass Fuse 5×20mm T12.5A for KIT4SAL DOMS2 Salt Chlorinator

Fluidra – Slow-Blow Glass Fuse 5×20mm T12.5A for KIT4SAL DOMS2 Salt Chlorinator

This is a genuine Fluidra replacement glass cartridge fuse — 5×20mm, 12.5A, time-delay (slow-blow) — sourced directly for the KIT4SAL DOMS2 multi-output salt chlorinator control unit. It provides essential overcurrent protection to the internal electronics of the chlorinator’s power board, safeguarding the unit against fault currents while tolerating normal inrush peaks during start-up.

Compatibility

This fuse is a factory-specified spare part for the Fluidra (Idegis) KIT4SAL DOMS2 salt chlorinator kit — a multi-cell system delivering combined outputs of 1×10A/2.3KW and 3×6.5A/1.5KW. Always verify the rating printed on the blown fuse before ordering; fitting an incorrect rating can void warranty and create a safety hazard.

Why genuine matters

Fluidra genuine fuses are matched precisely to the protection requirements of the DOMS2 control board. Third-party fuses with the same nominal rating may differ in breaking capacity or time-delay characteristics, potentially leaving the board under- or over-protected. Using the correct OEM part ensures the chlorinator continues to operate safely and within its original design parameters.

Installation

Fuse replacement is a straightforward procedure but should always be carried out with the chlorinator fully isolated from mains power. Identify the blown fuse visually or with a continuity tester, remove it from its holder, and press the new fuse firmly into place. If the replacement fuse blows immediately, there is an underlying fault — do not fit a higher-rated fuse; consult a qualified technician.
