The Hot Aerosol DFN-1P Fire Extinguishing Device is Din Rail Braker is a compact, automatic fire suppression solution specifically designed to protect electrical panels, control cabinets, switchboards, and enclosed electrical spaces. It uses hot aerosol fire suppression technology to rapidly extinguish fires at their early stage—without human intervention.

Upon activation, the DFN-1P releases a fire-suppressing aerosol that interrupts combustion, effectively extinguishing fires without damaging sensitive electrical equipment. Its self-activating design makes it ideal for unattended or high-risk electrical installations.

This compact and maintenance-free device is ideal for electrical panels, UPS systems, control cabinets, and ATMs, offering fast and reliable protection.
