<p>The purpose of the invention is designed such varistor fuse which include into one body contains varistor part or varistor (1) to protect electrical installations against overvoltage pulses and, consequently, from the effects of current surges, as well as electrical fuse (2) that is able to translate the current impact of increased voltages and break the constant increase in electrical current that could be occurred due to failure of varistor (1). In doing so, should such a varistor fuse not exceeded the dimensions and shapes meanwhile known and used protective equipment, especially electrical fuses. According to the invention is provided that each serial electrically connected to a round tubular coating (20) conceived the fuse (2) and also a round-tubular coating (10) based varistor (1) are inserted in alignment in each other.</p> |
