Pai nu se protejeaza semiconductori doar instalatia propriu zisa care cred ca poate face fata la socul pus pe ea care oricum va fi destul de scurt, deci eu sustin sugestia cu siguranta aia automata, pentru ce sa te complici cu tot soiul de improvizatii cand ai ceva atat de simplu si sigur la indmana.

Indiferent de solutie , pune si un varistor . Se poate intampla sa fie folositor ... ( amplasat bineinteles dupa siguranta , indiferent cum e realizata ) , mai ales daca ai consumatori scumpi . Varistorul e infim ca pret . Chiar daca nu va actiona niciodata , nu e o pierdere ... e ca un vaccin !

Prima, siguranta automata ( parca asa ii zice ) este cea mai simpla si sigura si o recomand.

...aia nu este ,,sigurantza automata''...in germana se intituleaza FI-Schalter sau Fehlerstromschutzschalter...RCD..(Residual Current Protective Device)http://de.wikipedia.org/wiki/FehlerstromschutzschalterEste un element de protectzie diferentziala...si e diferit de ..sigurantza automata..(SLS-Schalter)http://de.wikipedia.org/wiki/Selektiver_Leitungsschutzschalter...S-auzim numai de bine !

Da, modelul din poza asigura doar protectie diferentiala pentru un circuit de maxim 40A. E foarte bun pentru protectie la electrocutare dar poate fi problematic in circuite de test cu echipamente / montaje care pot avea curenti importanti (zeci mA) catre impamantare, astfel ca acest device va taia alimentarea (diferenta intre curentii pe cele 2 cai depaseste pragul setat, 30 sau 100mA).
