A practical guide for homeowners, shop owners and facility teams explaining why electrical protection and fire suppression are different layers of safety.
Many customers believe that if an MCB is installed, fire cannot happen. This is not fully correct. MCBs protect circuits from overcurrent and short circuit, but they are not fire extinguishing devices.

Why FireKavach helps
MCB / MCCB
Overload and short circuit current.
Cannot extinguish flame from loose connection, arcing or overheating if fire starts.
FireKavach activates from heat and suppresses fire inside the panel.
RCCB / ELCB
Leakage current to earth.
Cannot detect every overheating or arcing condition.
Adds fire suppression at the enclosure level.
Manual extinguisher
Nothing automatically; a person must see fire.
Cannot operate when nobody is present.
Automatic activation inside DB/panel.
Fire alarm
Smoke/heat depending on detector.
Gives warning but does not extinguish panel fire.
Suppresses the fire at source in a closed enclosure.
Common Causes of Electrical Panel Fire
Loose termination
Loose terminals create resistance heating, sparking and carbonisation.
Overloading
Excess load increases temperature of wires, busbars and protective devices.
Arcing
Arc faults can create very high local temperature even before a breaker trips.
Best Protection Strategy
The best approach is layered protection: correct electrical design, good quality components, periodic thermography, proper earthing, housekeeping, MCB/MCCB/RCCB protection, manual extinguishers and automatic panel-level suppression where required.
Simple message: MCB trips the circuit. FireKavach suppresses fire. Both solve different problems and should not be treated as replacements for each other.
