[Source] The Class-A thermal detonator was a model of thermal detonator manufactured by Merr-Sonn Munitions, Inc.. The detonator's power and range made it illegal for any use other than military purposes. Featuring a blast radius of up to 20 meters, it could be tuned to limit the radius depending on the situation. An activation panel was located on top of the detonator, in which an internal fusion reaction would be activated via the control panel. Powered by volatile baradium, the detonator was protected by a thermite casing.
