Abstract

Purely electronic device, planned to interrupt, in the shortest time possible the supply of direct current towards the user whether for the maximum absorption or for the highest temperature or owing to a short circuit, so avoiding the excessive heating (overheating) and the deterioration of the wire cables of feeding (which can be the cause of fire). The thermoelectric switch may have various thresholds of fixed intervention which can go from 100 m.A to 20, 30, 40 etc. A ampere or variable. The device has been planned for the purpose of having continually under control, when it is activated, both the current and the voltage of the DC current among accumulators in series or parallel coupling.
