Intrerupator MCCB solar 125A protectie sigura DC 500V
Intrerupatorul de circuit solar MCCB 2P-125A este conceput specific pentru instalatii fotovoltaice care opereaza la curent continuu, unde intrerupatoarele AC standard nu ofera protectie adecvata. Cu o tensiune nominala de 500V DC si curent nominal de 125A, asigura deconectarea rapida si sigura a circuitului in caz de supracurent sau scurtcircuit. Este potrivit pentru sisteme solare de dimensiuni medii si mari, acumulatori litiu si vehicule electrice.
Ce obtii cu acest produs
- Protectie reala pentru circuite DC — spre deosebire de intrerupatoarele AC, acest MCCB este proiectat sa intrerupa curentul continuu fara arc electric persistent, protejand echipamentele si instalatia
- Capacitate de rupere de 10kA — intervine eficient chiar si in cazul unor curenti de scurtcircuit ridici, prevenind deteriorarea invertoarelor, bateriilor sau cablajului
- Compatibil cu mai multe tipuri de sisteme — functioneaza in instalatii fotovoltaice, sisteme cu acumulatori litiu si vehicule electrice, fara modificari suplimentare
- Rezistenta termica extinsa — functioneaza corect intre -25°C si +70°C, inclusiv in tablouri expuse la temperatura ridicata sau in medii reci
- Tensiune de impuls de 6kV — ofera protectie suplimentara impotriva supratensiunilor tranzitorii frecvente in instalatiile solare
- Kit de montaj inclus — suruburile si capacele de protectie terminale sunt furnizate, astfel incat intrerupatorul este gata de instalare fara piese suplimentare
Cum functioneaza si cum se instaleaza
Intrerupatorul MCCB 2P-125A se monteaza pe sina DIN standard sau direct pe peretele tabloului electric folosind suruburile incluse in pachet. Conexiunile se realizeaza pe bornele marcate LINE (intrare) si LOAD (iesire), respectand polaritatea corecta a circuitului DC. Montajul nu necesita scule speciale, insa racordarea la un circuit fotovoltaic activ trebuie efectuata de o persoana cu calificare electrica, conform normativelor in vigoare.
Intrebari frecvente
Pot folosi un intrerupator AC obisnuit in locul acestui MCCB DC?
Nu este recomandat. Intrerupatoarele AC nu sunt proiectate sa stinga arcul electric generat de curentul continuu, ceea ce poate duce la deteriorarea dispozitivului sau incendiu. Acest MCCB este construit special pentru aplicatii DC.
Este compatibil cu un sistem solar de 48V sau 96V?
Da. Tensiunea nominala de 500V DC reprezinta limita maxima admisa, astfel incat orice sistem care opereaza sub aceasta valoare este compatibil, inclusiv sisteme de 48V, 96V sau 120V.
Se poate monta acest intrerupator pe sina DIN standard de 35mm?
Da, carcasa este prevazuta cu sistem de prindere compatibil cu sina DIN 35mm, utilizata in majoritatea tablourilor electrice rezidentiale 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.
