Meet E-Bulb, The World’s Smallest Fire Extinguisher, Integrated Into Electrical Appliances To Put Out Fires Before They Spread

This is the E-Bulb, “the smallest fire extinguisher in the world,” or a thermally-activated glass bulb that’s integrated into your electrical appliances – from your refrigerator, dryer, and TV that detects fires early by targeting them at their source. Developed by the JOB Group, based in Ahrensburg, Germany, the E-Bulb irreversibly cuts off the power supply, stops re-ignition, and extinguishes the fire.

While simple in nature, E-Bulb’s job is quite impressive. It’s technically a circuit interrupter with a fire extinguishing agent. This non-toxic, non-conductive extinguishing liquid is released into the device at the correct temperature and the Thermo-Bulb bursts. Instantaneously, the liquid converts into gas, as a result of cooling and partially by oxygen reduction.



Within seconds, the fire is extinguished. Since the current is interrupted, the electrical fire cannot be re-ignited. Compact yet powerful, at its smallest, the E-Bulb is only 2cm tall – so tiny that it can be hidden behind one Euro coin!
