摘要: A heat sensitive circuit interrupter comprising an electrical conductor (6,7) made from a material of predetermined melting temperature and encased in an electrically insulating sheath (1). The sheath is designed to withstand temperatures higher than the melting temperature of the conductor, and the conductor in its molten state flows within the sheath to break the electrical continuity of the conductor. The materials of the conductor and the adjacent portions of the sheath are selected to provide a contact angle for the molten conductor which is sufficiently large for the molten conductor to flow into separated drops. The conductor may be a lead/tin solder incorporating a flux.
