APPLICATION / FIREXNULL
Supplemental Fire Suppression for EV Charger Electrical Cabinets
Evaluate passive suppression for compatible EV charger electrical cabinets. Vehicle battery thermal runaway and charging cables are outside this scope.
FireXNull products are designed as supplemental protection, not as substitutes for code-required fire protection systems. Review technical documentation and confirm fit for the application.
APPLICATION OVERVIEW
EV Charging Infrastructure: Electrical Enclosures for Evaluation
Evaluate heat-activated localized suppression for compatible enclosed electrical equipment serving EV charging stations, with a focus on charger power cabinets, terminals and controls.
Application boundary: FireXNull products are passive, heat-activated, localized supplemental suppression products for compatible electrical equipment. They do not replace required electrical protection, detection, alarms, or fire-safety systems.
01 / EQUIPMENT CONTEXT
Focus on the Enclosed Electrical Equipment.
EV charging systems combine power conversion, electrical distribution, monitoring and contactor assemblies. Those components present different enclosure layouts and ventilation conditions that need review before any product is specified.
No industry incident statistic on this page is being used as evidence of FireXNull performance.
02 / CANDIDATE ENCLOSURES
Which Electrical Enclosures Can Be Evaluated?
Enclosure-mounted Sticker or Rope and connection-focused Tape are formats for engineering evaluation only, depending on cabinet geometry and electrical restrictions. Examples below are engineering evaluation candidates, not equipment-specific certifications or validated coverage claims.
- DC fast-charger power cabinetsEnclosed auxiliary distribution, control and eligible terminal areas.
- Contactor and switching enclosuresCompatible electrical connections and supporting components.
- Charging site distribution panelsLow-voltage distribution, branch circuits and terminations.
- Power-monitoring cabinetsEnclosed electronics and communications power connections.
- Charger auxiliary-control compartmentsElectrically enclosed control terminals and related wiring.
03 / PRODUCT FORMATS
Match the FireXNull Format to the Enclosure.
Compare the three heat-activated product families. A suitable product and model must be selected using the current approved TDS, enclosure details, electrical clearances and technical review.
FXN Sticker (S Series)
Adhesive-backed format for compatible smaller electrical enclosures with suitable upper-interior mounting surfaces.
Activation: 248°F ± 9°F (120°C ± 5°C)
Explore product →FXN Rope (R Series)
Flexible rope for eligible electrical cabinets with mounting points and required clearance.
Activation: 428°F ± 9°F (220°C ± 5°C)
Explore product →FXN Tape (T Series)
Cuttable wrap for selected compatible enclosed electrical terminals and connections.
Activation: 248°F ± 9°F (120°C ± 5°C)

|---|---|
| Enclosure geometry | Internal dimensions, mounting area and obstructions. |
| Operating conditions | Internal temperature, air leakage, ventilation, humidity and condensation. |
| Electrical safety | Voltage, live-part clearance, service access and manufacturer instructions. |
| Product documentation | Model-specific sizing, installation, replacement and safety documentation. |
04 / ENGINEERING FIT
What the Technical Review Must Confirm.
- Identify charger manufacturer/model and whether the space is service-accessible and enclosed.
- Document forced cooling and airflow, which may limit retained clean agent.
- Verify spacing to exposed conductors, power modules, fans and heat sinks.
- Check internal temperatures under maximum charging load and solar exposure.
- Obtain OEM/electrical engineering review and follow equipment isolation procedures.
The products operate without a power connection or detection wiring; they do not communicate an alarm signal. Installation should be performed only by qualified personnel on appropriately isolated and verified equipment.
05 / IMPORTANT LIMITATIONS
The Scope of This Application.
This application does not cover vehicle batteries, charging-cable fires, connector fires outside an enclosure, battery thermal runaway, or protection of an entire charging site. FireXNull does not replace electrical fault protection or required fire systems.
FireXNull contains FK-5-1-12, an electrically non-conductive clean agent. The clean agent itself does not leave residue, but other product materials or a fire event may. Electrical non-conductivity of the agent does not establish universal compatibility of the finished product with energized equipment.
06 / TECHNICAL FAQ
Frequently Asked Questions
Will FireXNull stop an EV battery or charging-cable fire?
No. The evaluation scope is compatible enclosed charger electrical equipment, not vehicle cells, battery thermal runaway, cable fires outside a cabinet or charging connectors in use.
Does FireXNull replace installed fire protection, alarms or electrical protection?
No. FireXNull is considered only as a supplemental localized layer in suitable electrical enclosures and does not replace code-required systems or maintenance.
Can FireXNull be installed while the equipment is energized?
Do not install on energized equipment. Qualified personnel must isolate and verify a safe work condition in accordance with the equipment manufacturer's instructions and applicable procedures.
Can this be used in outdoor or mechanically ventilated cabinets?
Potentially only after technical review. Internal temperatures, active airflow, cabinet leakage, humidity and condensation can make an enclosure unsuitable. Consult the current product-specific TDS and the equipment OEM.
How do we choose among Sticker, Rope and Tape?
Select by the electrical enclosure and intended placement. Sticker requires a compatible interior mounting surface; Rope requires appropriate secure routing and clearances; Tape may be considered for eligible electrical terminations. Final selection requires model-specific documentation and evaluation.
How is the product inspected or replaced?
Follow the selected model's approved TDS for inspection and replacement requirements. These are single-use products and must be replaced after activation. Qualified personnel should inspect equipment after any fire event before returning it to service.
Does the product notify a central alarm panel?
No. FireXNull suppression activates locally with heat and does not generate an alarm, notification or connection to an existing fire panel.
This page describes prospective evaluation applications, not completed field testing, certification or guaranteed suppression performance. Site and equipment-specific suitability must be demonstrated before installation.
Request an Electrical Enclosure Engineering Review
Send the equipment manufacturer and model, enclosure dimensions, operating conditions, and images or drawings of the intended mounting area. FireXNull can discuss whether a product-format evaluation is appropriate.
