The FuseBox HA20D is a compact DIN rail mountable heat-activated aerosol fire extinguisher. This automatic fire suppression solution is designed to provide added protection inside consumer units, distribution boards and other small enclosed electrical installations.

With no wiring or external power supply required, the unit activates automatically when temperatures reach 170°C (±10°C), rapidly releasing a condensed aerosol to suppress a fire at its source. Its compact MCB-sized design allows for simple installation using DIN rail or adhesive mounting, making it ideal for modern consumer units where space is limited.
