Detailed description

El bloc de fusibles compactes de làmines ST de 4 circuits Blue Sea 5045B-BSS està dissenyat per a la protecció dels circuits elèctrics marins. Aquest dispositiu integra quatre circuits per a fusibles ATO® i ATC® d'acció ràpida, oferint una solució de muntatge en superfície per als sistemes que requereixen una distribució d'energia fiable i segura.

Disseny i especificacions tècniques

Amb el seu disseny compacte, aquest bloc de fusibles permet l'entrada de cables per un únic costat, optimitzant l'espai disponible a bord. És "Ignition Protected", cosa que el fa segur per a ús en compartiments de motor de benzina, i compleix els requisits d'aïllament ABYC/USCG. Els busos i clips de fusibles estan fets de coure estanyat per a una millor conductivitat i resistència a la corrosió. El bloc accepta terminals de tipus anell o de forquilla i està equipat amb cargols de terminal #8-32 amb arandela de bloqueig integrada, així com un cargol roscat #10-32 per a l'alimentació principal. La seva tensió màxima de funcionament és de 32V DC, amb un amperatge màxim de 30A per circuit i 100A per bloc. El muntatge es realitza mitjançant cargols #8 (M4).

Posicionament en la gamma Blue Sea

El model 5045B-BSS, amb els seus quatre circuits, es posiciona com una opció per a instal·lacions més modestes o per a l'addició de circuits dedicats en comparació amb el seu germà gran, el Blue Sea 5046, que ofereix vuit circuits. Mentre que el 5046 està adaptat a necessitats de distribució més extenses, el 5045 destaca on l'espai és limitat i on es requereix un nombre reduït de circuits. Aquesta sèrie ST-Blade és una solució estàndard per a la protecció de circuits, reconeguda per la seva fiabilitat en entorns marins. Etiquetes estàndard i personalitzades estan disponibles per separat per a una identificació clara dels circuits. Els fusibles ATO o ATC es venen per separat.

« Compact protection solution for marine auxiliary circuits »

This compact ST-Blade 4-circuit fuse block from Blue Sea Systems is a practical solution for managing auxiliary circuits on recreational vessels or tenders. Its compact size and single-sided cable entry design make it particularly suitable for tight spaces such as helm consoles, battery compartments, or technical lockers where space is critical. The key advantage of this model is its "Ignition Protected" certification, a critical requirement for any electrical installation near an engine, including fuel compartments, eliminating the need for additional specific enclosures.

Compared to the 5046 model with 8 circuits in the same series, the 5045 is the relevant choice when a limited number of protections is sufficient for a given system, such as a group of navigation instruments, a bilge pump system, or deck lighting. It provides a solid foundation for creating isolated distribution points, simplifying troubleshooting and installation modularity. It is important to note that fuses must be purchased separately and that the 100A capacity per block, while sufficient for 4 x 30A circuits, must be respected for the main power line. This product is not intended to replace a full electrical panel for the entire vessel, but rather to complement an existing architecture or to equip secondary systems efficiently and safely.
