Beschreibung
Zusammenfassung:	A mass of small diameter ceramic pellets, for example of activated alumina, is located in a cylindrical metallic housing between its closed end and metallic heat absorbent material in the housing through the open end of which flow arc products incident to blowing of a fuse or similar circuit interrupting device. An apertured deflector disc overlies the pellets and prevents bypassing thereof along the inner surface of the housing. One or more metallic filter elements in the closed end of the housing place the interior thereof in limited communication with the atmosphere.
