Disclosed is an SMD micro mixed fuse with a thermal fuse function that stably operates at high voltage surges and can interrupt electrical current at a predetermined temperature. The SMD micro mixed fuse includes: a fuse substrate provided with a first electrode and a second electrode; a variator layer formed on a front surface of the fuse substrate; a first contact terminal and a second contact terminal respectively arranged at a first side and a second side of a front surface of the varistor layer and respectively connected to the first electrode and the second electrode; at least one thermal fuse that is arranged on the front surface of the variator layer, is not connected to the first and second contact terminals, but is connected to the fuse substrate; and a fusible element that is wire-bonded to the first and second contact terminals and is not connected to the thermal fuse.

A thermal detection plug for use with an electrical apparatus is provided. The thermal detection plug includes: a housing, a thermal cut-off, contact prongs, and supporting structures to effectively interrupt the flow of electrical power at the point of interface of between the power cord of an appliance and power receptacle. The thermal detection plug interrupts power based on a temperature detected at the interface point.

The invention relates to an assembly for a surge protection apparatus (10), comprising a disconnecting device (18) which includes a spring arm (20) having an end-side contact point (24) and a holding element (22). The holding element (22) and the contact point (24) are opposite each other in an initial position of the assembly (11). A thermally softenable material (26) is provided between the holding element (22) and the contact point (24) which connects the spring arm (20) both mechanically and electrically to the holding element (22). The assembly (11) has a remote signaling contact (50) which has a mechanical separating point (48). The spring arm (20), the holding element (22) and the remote signaling contact (50) are produced from a common stamped metal sheet (14). The stamped metal sheet (14) is at least partially insert-molded with a plastic material which forms a frame (16) The invention furthermore relates to a surge protection apparatus.
