Protectie sigura pentru circuite fotovoltaice DC 1000V
Siguranta MCB bipolara DC 1000V / 16A este conceputa exclusiv pentru protejarea circuitelor de curent continuu din instalatiile fotovoltaice. Intrerupe automat circuitul in caz de scurtcircuit sau suprasarcina, prevenind deteriorarea panourilor solare, invertorului si cablajului. Formatul compact pe sina DIN o face compatibila cu orice tablou electric solar standard.
Ce obtii cu acest produs
- Protectie dubla — intrerupe simultan polul pozitiv si negativ al circuitului DC, eliminand riscul de arc electric periculos specific curentului continuu
- Compatibila cu sisteme fotovoltaice de pana la 1000V DC — acopera configuratiile string standard fara componente suplimentare
- Declanseaza instantaneu la scurtcircuit — putere de rupere 10000A, protejeaza echipamentele scumpe inainte ca deteriorarea sa se produca
- Montaj rapid pe sina DIN 35mm — se fixeaza in tabloul solar in cateva minute, fara scule speciale
- Constructie robusta pentru exterior si medii dificile — rezista la variatii de temperatura si umiditate specifice instalatiilor solare
- Poate fi rearmata manual dupa declansare — nu necesita inlocuire dupa un incident, spre deosebire de sigurante fuzibile
Cum functioneaza si cum se instaleaza
Siguranta MCB bipolara DC 1000V monitorizeaza in permanenta curentul din circuitul fotovoltaic si declanseaza mecanic ambii poli simultan atunci cand detecteaza o suprasarcina sau un scurtcircuit, intrerupand complet fluxul de curent continuu. Instalarea se face prin simpla fixare pe sina DIN din tabloul electric solar, urmata de conectarea cablurilor DC la bornele de intrare si iesire — operatiune accesibila oricarui electrician autorizat. Dupa remedierea cauzei, siguranta se rearmaza manual prin actionarea manetei.
Intrebari frecvente
Pot folosi o siguranta MCB obisnuita de AC in locul acesteia pentru panouri solare?
Nu. Sigurante MCB standard sunt proiectate pentru curent alternativ si nu pot stinge arcul electric generat de curentul continuu la tensiuni ridicate, ceea ce prezinta risc major de incendiu. Este obligatorie folosirea unui MCB certificat DC.
Aceasta siguranta se potriveste cu tabloul meu solar existent?
Da, daca tabloul dispune de sina DIN 35mm standard — care este utilizata in aproape toate tablourile fotovoltaice de pe piata. Latimea de 2 module (aproximativ 36mm) trebuie sa fie disponibila in tablou.
Ce se intampla dupa ce siguranta s-a declansat — trebuie inlocuita?
Nu. Spre deosebire de sigurante fuzibile, MCB-ul se rearmaza manual dupa identificarea si remedierea cauzei care a provocat declansarea. Durata de viata nu este afectata de declansari normale.

Inspired to create a chair where the back and arms are moulded from a single piece of plywood
Inspired to create a chair where the back and arms are moulded from a single piece of plywood, Hecht and Colin describe employing a process similar to that a tailor might use to cut a pattern in fabric. This approach resulted in the beautiful structure wherein the moulded back and arms component is supported by a simple A-frame wood dowel construction. One of the benefits of this design is an increase in comfort due to natural movement in the plywood back.

Inspired to create a chair where the back
Made entirely of oak, the Bow Chair is comfortable, visually pleasing and brimming with character. The moulded plywood seat is unusually wide in proportion to its depth and a waterfall edge at the front softens contact with the hamstrings.
