Siguranta MCB bipolara DC 1000V pentru circuite fotovoltaice
Siguranta MCB de circuit fotovoltaic DC 1000V - 2P / 25A protejeaza instalatia solara impotriva scurtcircuitelor si suprasarcinilor, prevenind deteriorarea invertoarelor, cablurilor si panourilor fotovoltaice. Conceputa exclusiv pentru curent continuu, aceasta siguranta bipolara raspunde cerintelor specifice ale sistemelor fotovoltaice on-grid si off-grid. Formatul compact pe sina DIN o face potrivita pentru orice tablou electric solar, fara a ocupa spatiu inutil.
Ce obtii cu acest produs
- Protectie reala impotriva scurtcircuitului si suprasarcinii in circuitul DC — echipamentele solare raman ferite de avarii costisitoare
- Tensiune nominala DC 1000V si putere de rupere 10000A — compatibila cu instalatii fotovoltaice de capacitate medie si mare
- Montaj rapid pe sina DIN 35mm — nu necesita modificari ale tabloului electric, se fixeaza in cateva secunde
- Constructie bipolara 2P — intrerupe simultan ambii poli ai circuitului DC, eliminand riscul de arc electric rezidual
- Carcasa robusta rezistenta la temperaturi extreme si umiditate — functioneaza stabil in conditii de exterior prelungit
- Indicator vizibil de stare ON/OFF — starea sigurантei se citeste dintr-o privire, fara deschiderea tabloului
Cum functioneaza si cum se instaleaza
Siguranta MCB functioneaza prin decuplare termo-magnetica: la depasirea curentului nominal de 25A sau la aparitia unui scurtcircuit, mecanismul intern intrerupe automat circuitul DC, protejand instalatia. Instalarea se face prin simpla fixare pe sina DIN 35mm din tabloul electric fotovoltaic, urmata de conectarea cablurilor DC in bornele superioare si inferioare cu surubelnita. Nu sunt necesare scule speciale sau cunostinte avansate de electricitate, insa conectarea la instalatia electrica trebuie realizata de un electrician autorizat.
Intrebari frecvente
Poate fi folosita aceasta siguranta si pentru curent alternativ (AC)?
Nu. Siguranta este proiectata exclusiv pentru circuite DC — utilizarea pe circuite AC poate duce la functionare defectuoasa si prezinta risc de securitate.
Cate panouri solare pot fi conectate pe aceasta siguranta de 25A?
Numarul de panouri depinde de curentul de scurtcircuit (Isc) al fiecarui panou si de configuratia sirului; ca regula generala, suma curentilor de scurtcircuit ai panourilor conectate nu trebuie sa depaseasca 25A.
Este compatibila cu tablouri electrice standard?
Da, siguranta se monteaza pe orice sina DIN 35mm standard, prezenta in aproape toate tablourile electrice fotovoltaice si industriale.

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.
