The invention relates to a type-II overvoltage protection device having a varistor and a protective element, wherein the protective element has a first contact for connecting to a first potential of a supply network and a second contact that is connected to a first contact of the varistor, wherein the varistor further comprises a second contact for connecting to a second potential of a supply network, wherein the protective element has a fuse element that connects the first contact and the second contact of the protective element, wherein the protective element further comprises a third contact that is connected to the second contact of the varistor and is arranged so as to be near to but electrically insulated from the fuse element, wherein the fuse element has a constriction in the proximity of the neighboring contact, with the constriction being embodied such that the fuse element has an electrically conductive fluxing agent in the proximity of the constriction, with the fluxing agent having a lower fusion point than the fuse element itself, so that pulses corresponding to a load below the type-II rating do not result in a lasting change in the constriction, wherein the constriction, in conjunction with the fluxing agent, is dimensioned such that pulses corresponding to the limit range of the type-II rating result in the fusing of the fluxing agent into the fuse element, and wherein pulses corresponding to a load that is stronger and/or of greater duration than the type-II rating of the varistor result in the immediate disconnection of the fuse element.

One embodiment of the present invention includes a hard-coded first device ID. The embodiment also includes a set of fuses that represents a second device ID. The hard-coded device ID and the set of fuses each designate a separate device ID for the device, and each device ID corresponds to a specific operating configuration of the device. The embodiment also includes selection logic to select between the hardcoded device ID and the set of fuses to set the device ID for the device. One advantage of the disclosed embodiments is providing flexibility for engineers who develop the devices while also reducing the likelihood that a third party can counterfeit the device.

Exemplary embodiments of the present invention are directed to a circuit protection device, A circuit protection device may comprise a housing defining a cavity and a metal oxide varistor (MOV) disposed within the cavity. The circuit protection device may further comprise a first terminal electrically attached at a first end to the MOV by solder and extending outside of the housing at a second end. An arc shield is disposed within the housing between the first end of the first terminal and at least partially over the solder. The circuit protection device may further comprise a spring configured to bias the arc shield against a micro switch having an indicator portion disposed at least partially outside of the housing. When a voltage surge condition occurs, the MOV changes from a non-conductive state to a conductive state and current flows between the first terminal and a second terminal where the heat generated by the current flowing through the varistor melts the solder and the first end of the first terminal electrically separates from the varistor.
