Snap-on Hot Aerosol Automatic Fire Suppression Sticker 40g Agent 0.4m³ Coverage 170℃ Thermal Activation EN 15276 Certified DIN Rail & Self-Adhesive Mount 10-Year Lifespan for Meter Box Distribution Ca

This snap-on hot aerosol automatic fire extinguishing device, widely called fire suppression sticker, is a compact passive fire safety unit developed for enclosed electrical cabinets and meets European EN fire protection standards. Loaded with 40g high-efficiency aerosol fire agent, each unit weighs 115g and provides effective fire suppression for 0.4m³ enclosed space at standard 100g/m³ extinguishing density. Working without external power, the device will activate automatically once ambient temperature inside the cabinet exceeds 170℃ to release aerosol and put out initial electrical fires. The shell surface temperature is limited to maximum 200℃ during discharge, effectively preventing secondary ignition of plastic cables and cabinet components. Two installation solutions including DIN rail snap mounting and self-adhesive back glue satisfy new project assembly and cabinet renovation requirements. It features ultra-long 10-year standby service life and holds authoritative EN 15276-1:2019, EN 15276-2:2019 certifications. Suitable for installation inside meter boxes, complete distribution cabinets, waterproof charging boxes and motor control cabinets to realize 24-hour unattended automatic early fire suppression.

1. 170℃ Passive Thermal Trigger, Power-Free 24H Unattended Protection
   Equipped with high-sensitivity temperature sensing element, no power supply or wiring required. When cabinet internal temperature rises above 170℃, the device activates instantly. Aerosol is released to isolate oxygen and cool burning sources, suppressing initial fires automatically without staff monitoring.

2. Dual Installation Options Fit All Construction Scenarios
   DIN rail snap-on design can be firmly installed on standard electrical guide rails for new distribution cabinet projects. Self-adhesive back glue enables quick installation on smooth inner walls without drilling, ideal for safety upgrade of existing finished electrical cabinets.

3. Controlled 200℃ Shell Temperature, Avoid Secondary Fire Hazards
   The outer shell temperature will not exceed 200℃ during fire suppression, which is much lower than ignition temperature of plastic wires and cabinet materials. It prevents surrounding combustible parts from being ignited and eliminates secondary fire risks inside narrow closed cabinets.

4. 40g Sufficient Agent for 0.4m³ Space, Uniform Fire Suppression Without Dead Zones
   Adopting 40g aerosol agent matched with standard 100g/m³ extinguishing density, perfectly covering 0.4 cubic meter enclosed space. Ultra-fine aerosol particles spread fully in the cabinet to realize comprehensive fire fighting effect.

5. 10-Year Ultra-Long Standby Service Life, Low Maintenance Cost
   Integrated fully sealed structure ensures stable performance for up to 10 years after installation. No regular inspection, maintenance or frequent replacement, greatly reducing long-term fire safety expenditure for property management, factories and engineering projects.

6. EU EN 15276 Dual Standard Certified, Qualified for Global Export
   Passed strict fire performance testing of EN 15276-1:2019 and EN 15276-2:2019. Stable and reliable fire suppression performance complies with international electrical fire safety standards, suitable for overseas engineering projects and wholesale export.

7. Compact Lightweight Structure, Will Not Affect Internal Wiring Layout
   Single unit only 115g with small occupied space. It can be flexibly arranged inside various electrical enclosures without interfering with wiring, circuit breakers and other internal components.

This snap-on hot aerosol fire suppression sticker is specially designed to solve hidden fire risks from overheating and short circuits in unattended sealed electrical equipment. It adopts passive temperature induction startup technology and operates independently without external power supply, responding rapidly to abnormal high temperature before open flames occur and curb fire accidents at early stage.

Filled with 40g high-performance hot aerosol extinguishing agent, the product follows standard 100g/m³ extinguishing density corresponding to 0.4m³ independent protection volume. After activation, micron-sized aerosol diffuses evenly inside the cabinet to cut off oxygen and rapidly cool overheated components, effectively stopping fire spreading. The shell surface temperature is strictly controlled below 200℃ during working process, avoiding secondary combustion caused by contact ignition of plastic cables and cabinet housing.

Two practical installation methods are available for different demands. DIN rail snap-on version can be tightly fixed on standard electrical guide rails inside distribution boxes, shock resistant and anti-drop for long-term use. Self-adhesive back glue version supports quick sticking on smooth surfaces of charging boxes and meter boxes, no damage to cabinet structure during renovation installation.

With dual authoritative EN 15276 series fire certifications and 10 years long standby cycle, the product can be kept on standby for a decade safely. Widely applied in residential meter boxes, factory motor control cabinets, commercial distribution cabinets and outdoor waterproof charging boxes, it becomes a standard matching fire safety component for all kinds of closed electrical facilities.
