Thermal fuse, especially for thermal connection to heater, has trigger element with opening spring electrically insulated from surroundings in housing body with melting material outflow chamber(s)

摘要

The device has first and second connection contacts with first and second fixed contacts in an approximately rotation-symmetrical insulating housing body and a trigger element with an opening spring acting on a moving contact arranged between the contacts and a melting material. The trigger element is electrically insulated from the surroundings in the housing body, which has at least one outflow chamber for the melting material. The device has first and second connection contacts (10,20) with first and second fixed contacts (11,21) in an approximately rotation-symmetrical insulating housing body (3040) and a trigger element (50) with an opening spring (51) acting on a moving contact (52) arranged between the first and second fixed contacts and a melting material (54). The trigger element is electrically insulated from the surroundings in the housing body, which has at least one outflow chamber for the melting material.
