How Does an In-Cabinet Fire Suppression System Operate?
In-cabinet fire suppression systems detect localized thermal runaway or arc flash events directly inside electrical switchgear. Without waiting for smoke to exit the cabinet or requiring total room flooding, they deploy solid potassium micro-aerosol directly into the micro-environment, extinguishing fires in under 10 seconds through free-radical chemical interruption.
Why Electrical Switchboard Fires Occur
Over 70% of industrial electrical fires originate from loose terminal connections, harmonic overheating, or insulation degradation inside closed enclosures. Room-level gas or water systems react only after smoke migrates through cabinet vents, causing catastrophic equipment damage before activation.
Micro-Aerosol Combustion Chain Interruption
When energized, GuardX solid potassium carbonate ($K_2CO_3$) aerosolizes into microscopic particles. These particles scavenge free radicals ($H^+$ and $OH^-$) from the flame zone (forming $KOH$). Because it does not displace oxygen and is certified 24 kV non-conductive, it extinguishes fires while live circuits remain powered without thermal shock.
