Operating at DC 550V with an 8KV impulse voltage rating and a 10KA breaking capacity, it ensures reliable overload and short circuit protection. Its flame retardant thermoset casing enhances safety, while its compact design fits seamlessly into modern solar panel grid systems, making it an essential safeguard for your renewable energy setup. ## Description DC circuit breaker is mainly used to distribute electric energy and protect lines and power equipment from overload, short circuit, undervoltage and other faults, can also be used as motor infrequent starting and overload, short circuit, undervoltage protection.When the circuit overload or short circuit and other causes of overcurrent, the circuit breaker will be immediately disconnected, so as to protect the circuit.Moulded case circuit breaker is made of thermosetting material with good flame retardant, will only gradually carbonize and will not burn even if meets open flame, more safe.MCCB solar battery protection switch environmental usage temperature from ‑10℃ - 50℃, suitable for more extreme environment.The solar battery protection switch has the characteristics of small size, with short circuit protection, overload protection, flame retardant shell, high breaking, short arc and so on.

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. ## Frequently Bought Together - Heschen DC Molded Case Circuit Breaker MCCB, HSM1PV-125, 2 Poles, DC550V 125A, Photovoltaic Circuit Breaker, for Solar PV System Solar Panels Grid System - CHTAIXI DC Miniature Circuit Breaker, 2 Pole 1000V 25 Amp Isolator for Solar PV System, Thermal Magnetic Trip, DIN Rail Mount, Chtaixi DC Disconnect Switch C25 - Heschen DC Molded Case Circuit Breaker MCCB, HSM1PV-250, 2 Poles, DC550V 150A, Photovoltaic Circuit Breaker, for Solar PV System Solar Panels Grid System --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/634871506-heschen-dc-molded-case-circuit-breaker-mccb-2-poles-dc550v](https://www.desertcart.gr/products/634871506-heschen-dc-molded-case-circuit-breaker-mccb-2-poles-dc550v) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-07-12*
