L’interruttore MCCB è utilizzabile come magnetotermico per carichi in corrente continua fino a 550V e 125A, lo si può utilizzare in diversi ambiti tra cui ad esempio un pacco batterie di un impianto fotovoltaico oppure qualsiasi altro utilizzo in cui serva proteggere un carico DC importante.L’MCCB ha una levetta per armare e disarmare il meccanismo interno, è abbastanza dura ma funziona egregiamente, il fatto che sia dura da armare normalmente significa che il meccanismo interno utilizza delle molle rigide e adeguate al carico che devono sezionare.Sul corpo troviamo poi un pulsante rosso che se premuto simula l’attivazione del circuito interno e permette di disarmare l’interruttore, funziona nello stesso modo di quando il magnetotermico salda e scollega il carico in caso di sovraccarico o cortocircuito.Quando si preme il pulsante rosso oppure quando il magnetotermico salta da solo per proteggere ciò a cui è collegato, prima di poterlo riattivare bisognerà portare la levetta in posizione OFF e poi alzarla verso la posizione ON. Non so il motivo esatto ma penso sia per motivi di sicurezza in quanto permette al circuito di attivarsi anche se la levetta è bloccata.Il peso e le dimensioni sono importanti, può essere fissato ad un muro o ad una parete di qualsiasi tipo tramite 2 fori posti tra i contatti.Sul retro ha un foglio isolante per migliorare ulteriormente l’isolamento e rendere possibile l’installazione anche in armadietti metallici.I contatti sono larghi e l'installazione è molto semplice quando si utilizzano i capicorda ad occhiello, le viti hanno una rondella spaccata già inclusa per evitare che si allentino anche se ci sono vibrazioni dove viene installato.A livello di qualità è a mio parere buono e per ora funziona a dovere, l'unica pecca che ho notato è che si scalda abbastanza durante l'uso con carichi attorno ai 50-60A.

Review of the DC Molded Case Circuit Breaker MCCB, HSM1PV-125I recently purchased the DC Molded Case Circuit Breaker MCCB, HSM1PV-125, for my solar photovoltaic (PV) system, and I have mixed feelings about it.First impressions are important, and this breaker certainly feels solid and well-constructed. The weight of the unit gives an impression of durability, which is essential for electrical components. However, the fact that it is manufactured in China raises some concerns about overall quality control, which has been echoed by other users.One of the significant issues mentioned in reviews is the heat generation when the unit is under load. As someone who values safety and efficiency, this is a red flag for me. The last thing you want in a solar setup is for a breaker to overheat, which can compromise safety and potentially damage the components of your system. Although I’m currently operating it at a fraction of its rated load (DC550V, 125A), I still find it prudent to keep an eye on the temperature during operation.I appreciate that the MCCB is designed for photovoltaic applications; it’s crucial that we use components specifically suited for solar systems. However, the concerns around heating issue are troubling. Users with higher loads should definitely invest in a temperature gauge to monitor the breaker during operation. If poor-quality materials are in play, that could lead to premature failure or, worse, a safety hazard.In light of these considerations, while I feel the HSM1PV-125 is a decent option for low to moderate loads, I would be hesitant to recommend it for more demanding applications without proper monitoring. It's a gamble—one that could pay off if it remains cool and functions reliably, but one that carries a risk based on the feedback from other users.In conclusion, while I appreciate the construction and intended application of this circuit breaker, I can’t fully endorse it without acknowledging its potential pitfalls. If you decide to go with the HSM1PV-125, just be sure to monitor the heat and use it judiciously.

I got this to help you with my DC incoming voltage from my solar panel raise and I need to get a few more before I can get everything DIN mountedEvery single looks very nice about it, but you will not find UL Certification audit and as long as you’re OK with that, I have they recommend you buy this as it is heavy quality is very well filled
