Protects where fires start
Room detection cannot see inside a closed cabinet until it is far too late.

Electrical Panel Fire Protection
Deal with the fire inside the cabinet, in the first seconds — tube-based suppression that needs no power, no wiring and no detector to fail.
Overview
What Is Panel Fire Protection?
A large share of industrial fires begin inside electrical enclosures, for unremarkable reasons: a loose termination heating over months, a contactor welding itself, insulation degrading, or dust bridging a gap that was adequate when the panel was new.
What makes them serious is where they start. Inside a closed metal cabinet a fire is invisible, the smoke is contained, and nothing in the room has any reason to react until the enclosure has been breached. Tube-based suppression deals with it at source: a pressurised polymer tube is routed past the components most likely to fail, and bursts at the point of highest heat.
- Protection inside the enclosure The detection tube runs past the terminations and components that actually fail.
- It acts at the hot spot The tube bursts where the heat is and releases agent directly there.
- No power and no wiring Nothing to lose in exactly the fault condition being protected against.
- Retrofits to what you have Fits existing panels, racks and cabinets without rebuilding the board.
Operation
How Panel Protection Works
01
Route the tube
Pressurised detection tubing is installed through the enclosure, past the risk.
02
Sense by heat
Rising temperature at any point weakens the tube wall at that point.
03
Burst and release
The tube ruptures at the hot spot and the pressure drop opens the cylinder.
04
Suppress at source
Agent discharges inside the cabinet before the fire can leave it.
Benefits
Why Choose Panel Fire Protection?
Acts in seconds
Suppression happens inside the enclosure before cable trays are involved.
No dependency on supply
No power, wiring or control panel — nothing to fail with the circuit it protects.
Retrofits easily
Fits existing boards and racks without a rebuild or a long outage.
Equipment stays serviceable
Clean agent options leave the surviving board usable.
Low cost against the risk
Small relative to the panel, and very small against the production behind it.
Applications

Configuration
Inside a Panel Protection System
- Detection tubing pressurised polymer tube routed past the components most likely to fail.
- Agent cylinder sized to the enclosure volume and mounted inside or alongside it.
- Direct or indirect arrangement the tube delivers the agent itself, or triggers a separate nozzle.
- Pressure gauge and indication so the system's readiness is visible without testing it.
- Optional alarm interface to the fire panel or BMS where the project design calls for it.
- Design, commissioning and maintenance including enclosure survey and pressure checks under AMC.

Compliance
System Integration and Compliance
Standards and approvals
Panel and enclosure suppression is applied under Part 4 of the National Building Code (NBC 2016) as part of the site's fire protection, with the electrical installation and enclosure requirements following the relevant IS and IEC practice for the switchgear concerned.
Insurers frequently set specific conditions for switchgear and control room protection, and the installed system forms part of what is assessed.
We confirm agent and component approvals against the certification held by the specific system proposed, and against your consultant's specification.
FAQ
Frequently Asked Questions
What facility and maintenance teams usually ask about panel protection.
Still have a question?
Speak directly with one of our fire safety engineers.
Call +91 88795 33000How does it detect a fire inside the panel?
The detection tube is the sensor. It is pressurised, and at the point of highest heat the tube wall weakens and bursts — which is both the detection and the trigger.
Does it need a power supply?
No. There is no power, no wiring and no control panel, which matters because the fault being protected against is an electrical one.
Will it damage the equipment?
Clean agent options leave no residue and do not conduct, so the surviving board remains serviceable.
Can it be fitted to an existing panel?
Yes. The tube and a small cylinder fit inside or alongside existing boards and racks, usually without a long outage.
Direct or indirect — what is the difference?
In a direct system the tube itself delivers the agent at the burst point. In an indirect system the pressure drop opens a valve and discharges through a separate nozzle, which suits larger enclosures.
How do I know it is still charged?
A pressure gauge gives a visible indication of readiness, and pressure checks are part of the maintenance schedule.
What do you need to quote a project?
The number and size of enclosures, what is inside them, whether they are energised during work, and photographs or drawings if you have them.
