Products Description
Distribution cabinet fire extinguishing device
Ideal for distribution cabinet fire protection, the QRR0.02G/S-WK Rail-Mounted Aerosol Fire Extinguishing Device is a compact,high-efficiency fire suppression solution tailored to electrical equipment scenarios. Engineered in strict compliance with the XF499.1-2010 national standard, this device delivers reliable performance in extreme environments, ensuring rapid fire control without damaging sensitive electrical components.
Crafted for long-term durability, the device boasts an impressive 10-year service life, minimizing maintenance costs and
maximizing operational uptime for your electrical systems. It operates stably across an ultra-wide temperature range of -50°C to 90°C, with a shell temperature resistance of ≤250°C, making it suitable for harsh working conditions from frigid outdoor installations to high-heat indoor electrical rooms.
At its core, the device features a high-performance aerosol formulation with magnesium nitrate and potassium nitrate (50%-58%) as the primary oxidizers. With a fire extinguishing density of 100g/m³, it quickly generates fire-suppressing aerosol particles upon activation, effectively smothering fires by interrupting the combustion chain reaction—all without leaving residue that could harm circuit boards or electrical contacts.
Safety is prioritized in its design, with clearly defined nozzle thermal spacing requirements to prevent heat-related hazards
during operation: maintain a 0.3m distance for environments up to 400°C, 0.5m for 200°C scenarios, and 0.8m for 75°C applications.Its rail-mounted design enables easy, space-saving installation directly inside distribution cabinets, ensuring seamless integration with existing electrical setups and enabling immediate response at the fire source.
Whether for low-voltage switchgear, control cabinets, or distribution panels, the QRR0.02G/S-WK provides a cost-effective,
eco-friendly, and maintenance-free fire protection solution that safeguards your critical electrical assets.
