This type is also known as a multi-purpose fire extinguisher.
It is called an "ABC" extinguisher because it is effective against Class A (ordinary combustibles), B (flammable liquids), and C (electrical) fires.
The powder agent used is a combination of monoammonium phosphate and ammonium sulphate, which smothers the fire by absorbing fuel molecules.
It is available in various capacities, such as 2k models.
It features a pressure gauge for monitoring readiness and simple operating instructions for user-friendly operation.
