Electrical panel fire suppression works best when protection is positioned where a fire can actually begin: inside the electrical enclosure itself. Flarex is a compact automatic aerosol fire-suppression device designed to add localized protection inside electrical panels, breaker panels, control cabinets and other suitable enclosed electrical spaces.
For homeowners, electricians, facility managers and businesses in the United States, the appeal is straightforward: Flarex is designed to respond automatically inside a protected enclosure, without waiting for someone to discover the fire and reach for an extinguisher.

What Is Flarex?
Flarex is an automatic aerosol fire-suppression device intended for localized protection of enclosed spaces. Instead of protecting an entire room from a remote location, the device can be positioned inside or directly at the electrical enclosure that needs protection, subject to the product's installation and sizing requirements.
The concept is simple: if an electrical fault develops inside a cabinet, localized protection can respond in the same confined space where the incident begins.
Flarex uses an aerosol extinguishing agent and a non-pressurized canister design. Depending on the model and configuration, activation can be thermal and/or electrical. For autonomous thermal applications, a heat-sensitive activation element can initiate the device without requiring manual intervention.
Why Electrical Panels Need a Different Kind of Fire Protection
Electrical panels, breaker panels and control cabinets concentrate wiring, terminals, breakers and other components into a relatively small space. Loose connections, damaged components, overheating or electrical faults can create an ignition source inside an enclosure that may not be immediately visible from outside.
Portable fire extinguishers remain important, but they depend on someone being present, recognizing the problem and acting. A localized automatic system addresses a different part of the risk: response inside the enclosure before manual intervention is available.
That does not make Flarex a replacement for required alarms, extinguishers, sprinklers or other code-mandated fire protection. It is an additional layer of protection designed for a specific risk area.
How Does Flarex Work?
In an appropriate installation, Flarex remains passive during normal operation. When the applicable activation conditions are reached, the device initiates and releases its aerosol extinguishing agent into the protected enclosure.
- Detection / activation: the thermal activation element responds when its specified activation condition is reached.
- Automatic initiation: the suppression process begins without requiring a person to operate the device.
- Localized discharge: the aerosol is released into the enclosed protected volume, where it is intended to act on an incipient fire.
The protected space, ventilation openings, placement and product model all matter. Correct sizing and installation are therefore essential.
6 Key Benefits of Flarex for Electrical Fire Protection
1. Automatic response
The central advantage is that Flarex can respond without waiting for someone to notice the fire. This is particularly useful for electrical enclosures that may be unattended for long periods.
2. Protection close to the source
Flarex is designed to be placed in the protected enclosure, so the extinguishing agent is released where a fire may originate rather than from across the room.
3. Compact design
Electrical cabinets are often crowded. The compact Flarex format allows localized protection to be integrated where a conventional cylinder-and-pipe suppression system may be impractical.
4. Autonomous thermal operation
For configurations using autonomous thermal activation, the suppression response does not depend on a person being present or on a separate manual trigger. Always follow the instructions for the specific Flarex model being installed.
5. Designed for enclosed-space protection
Aerosol suppression is particularly suited to defined enclosed volumes. This makes correct enclosure sizing, placement and control of openings an important part of the application.
6. Useful across residential and commercial settings
The same principle can apply to a residential breaker panel, a commercial electrical cabinet or an industrial control enclosure, provided the selected product and installation are suitable for the protected volume and environment.
Where Can Flarex Be Used?
Typical applications for localized electrical enclosure fire protection can include:
- Residential breaker and electrical panels
- Commercial electrical cabinets and distribution boards
- Control panels and automation cabinets
- Machinery electrical enclosures
- Utility and equipment cabinets
- Other suitable enclosed compartments where the product's installation conditions can be met
Every installation should be assessed individually. The enclosure volume, ventilation, operating temperature, component layout and applicable fire-safety requirements can affect suitability.
How to Choose the Right Flarex Setup
The most important starting point is the internal volume of the enclosure you want to protect. Measure the usable internal length, width and height of the cabinet and compare that volume with the rated protected volume of the relevant Flarex model.
Do not choose a unit based only on the outside dimensions of the panel. Openings, ventilation and the internal arrangement of equipment can also matter. If the enclosure is unusual or heavily ventilated, check the technical documentation or ask for application support before purchasing.
Not sure what size you need?
Send Distreo the internal dimensions of the electrical enclosure and a photo of the panel. We can help identify the most appropriate Flarex configuration for the application.
What U.S. Buyers Should Know About Standards and Compliance
Flarex product documentation references EN 15276-1:2019 and EN 15276-2:2019 for aerosol fire-extinguishing systems. These are European standards. For installations in the United States, buyers, installers and system designers should also verify all requirements that apply to the specific building, occupancy and jurisdiction, including requirements imposed by the relevant authority having jurisdiction (AHJ).
Flarex should be treated as an additional localized fire-protection measure. It does not automatically replace fire extinguishers, fire detection, sprinkler systems or other protection required by applicable codes, standards, insurers or local authorities.
What Does the Flarex Package Look Like?
The product is supplied as a compact unit with installation components and documentation. Always review the model-specific instructions before installation and confirm that the selected mounting position and protected volume are appropriate.
Frequently Asked Questions About Flarex
Does Flarex activate automatically?
Flarex supports automatic activation configurations. In an autonomous thermal setup, the device is designed to initiate when the specified activation condition is reached, without requiring a person to operate it.
Is Flarex designed for electrical panels?
Yes. Electrical panels, distribution boards and control cabinets are among the intended enclosed-space applications shown in the Flarex product documentation and media. The specific enclosure still needs to meet the product's sizing and installation requirements.
Does Flarex replace a fire extinguisher or fire alarm?
No. Flarex provides localized suppression and should be used as part of a broader fire-safety strategy. Required extinguishers, alarms, sprinklers or other systems remain subject to applicable codes and local requirements.
How do I know which Flarex model I need?
Start with the internal protected volume of the enclosure. Then match that volume to the rated coverage of the appropriate Flarex model and account for the installation conditions described in the technical documentation.
Can Flarex be used in a home?
Flarex can be considered for suitable residential electrical enclosures as an additional layer of localized protection. Installation suitability should be evaluated for the specific panel and local requirements.
Where can I buy Flarex in the United States?
Flarex is available from Distreo USA. The product page includes current purchasing information and technical details.
