Intrerupator industrial 250A tripolar pentru protectie circuite principale
Acest intrerupator general tripolar NF-250A asigura protectia si controlul circuitelor electrice de mare putere in fabrici, uzine si instalatii industriale. Ideal pentru motoare puternice, pompe industriale, linii de alimentare si echipamente de productie, ofera comutare sigura pana la 600V cu capacitate de intrerupere de 25kA la 220V AC.
Ce obtii cu acest produs
- Protectie robusta pentru circuite de pana la 250A — gestionezi motoare industriale si echipamente de putere fara risk de suprasarcina
- Maneta ON-OFF clara si buton de resetare integrat — repornire rapida dupa deconectare, fara interventie complexa
- Pastile de contact din aliaj de cupru — conductivitate superioara si durabilitate la cicluri frecvente de comutare
- Carcasa ABS ignifugata — rezistenta termica si electrica conform standardelor industriale, siguranta crescuta in medii exigente
- Montare rapida pe surub — kit complet cu suruburi pentru prinderea cablurilor, instalare stabila in tablouri electrice
- Compatibilitate triplu standard — functioneaza conform JIS si IEC, adaptat pentru diverse configuratii de tensiune industriala
Cum functioneaza si cum se instaleaza
Intrerupatorul se monteaza in tabloul electric principal pe sina DIN sau prin fixare directa cu suruburi. Cablurile de alimentare se conecteaza pe bornele superioare, iar cele de iesire pe bornele inferioare, utilizand suruburile din kit. Maneta permite deschiderea si inchiderea manuala a circuitului, iar butonul rosu de resetare deblocheaza mecanismul dupa o deconectare automata cauzata de suprasarcina. Instalarea necesita electrician autorizat conform normelor de protectie a muncii.
Intrebari frecvente
Pot folosi acest intrerupator pentru un motor trifazat de 75kW?
Da, intrerupatorul suporta curentul necesar unui astfel de motor la tensiunile industriale standard 380-400V, cu conditia respectarii capacitatii de 250A.
Cum stiu cand sa apeși butonul de resetare?
Butonul roseste sau iese din pozitie dupa o deconectare automata. Apesi resetarea doar dupa verificarea si eliminarea cauzei care a dus la intrerupere.
Se poate monta in tablou electric vechi cu montaj pe surub, nu pe sina DIN?
Da, constructia permite fixare directa prin gaurile de prindere cu suruburi, independent de sina DIN.

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.
