Understand exactly what happens when FireKavach activates, how the aerosol cloud is formed, why a closed electrical panel matters and what buyers should check before installation.
FireKavach is designed as an automatic panel-level fire suppression device. Its role is to act early inside the enclosure where electrical fires usually begin.
The solid aerosol-forming compound is not stored under pressure. During activation, the internal compound reacts and produces hot gases carrying fine aerosol particles. These particles behave like smoke or mist inside the panel, spreading across the available enclosed volume.
The suppression happens because the aerosol interacts with the flame chemistry. The particles and active species reduce heat and consume flame radicals that are needed to keep combustion alive.
Aerosol suppression depends on concentration. When a DB or panel door is closed, the aerosol cloud remains inside and reaches the required concentration faster. If the panel is open, broken or heavily ventilated, the aerosol can escape and the suppression performance may reduce.
| Condition | Effect |
|---|---|
| Closed DB/panel | Best chance for rapid aerosol concentration build-up. |
| Open panel door | Aerosol may escape and concentration may reduce. |
| Very large enclosure | Correct device sizing is required. |
| Outdoor rain exposure | Device should be protected as per installation guidance. |
DB boxes, electrical panels, control cabinets, small enclosures, solar ACDB/DCDB, EV charger cabinets and UPS panels.
Large panels, ventilated cabinets and special hazard areas should be checked for sizing, enclosure volume and installation location.
