Detailed description

Disainitud keerukate merealuste elektripaigalduste jaoks pakub Blue Sea 5032B-BSS jagudiviga kaitselülitite plokk erinevate vooluringite eraldiseisvat juhtimist. See võimaldab ühel plokil kombineerida kuus pidevalt (24 tundi) toitvaid vooluringe ja kuus lülitatavaid vooluringe, optimeerides seeläbi kaablite paigutust pardal. Süsteem asendab vajaduse kahe eraldi ploki järele pideva ja kontrollitud toite jaoks, lihtsustades oluliste seadmete, nagu pumba ja navigatsioonisüsteemide, integreerimist.

Omadused ja tehnilised andmed

5032B-BSS on mõeldud maksimaalse pinge 32V alalisvoolu jaoks, iga vooluringi kohta kuni 30A ning koguvoolu kuni 100A (ilma ületamata 80A ühe laadimisgrupi kohta). Kasutab ATO® või ATC® tüüpi kaitselüliteid, mis on laialdaselt kättesaadavad. Ühendused toimuvad #8-32 kruvidega kontaktidega, millel on lukustavad alusplaadid haruühenduste jaoks, sobides 10–16 AWG (6–15 mm²) juhtmete jaoks. Peatoide ühendatakse #10-32 kruvidega, mis sobivad 4–6 AWG (25–16 mm²) juhtmete jaoks, kindlustatud roostevabast terase alusmutteritega. Soovitatav keerdemomenti on 2,71 N-m (24 in-lb) #10 kruvidele ja 2,03 N-m (18 in-lb) #8 kruvidele.

Disain ja integreerimine

See kaitselülitite plokk on varustatud tinatud vasest siinide ja kaitselülitite klipsudega, tagades juhtivuse ja korrosioonikindluse, mis sobivad merekeskkonda. Läbipaistev isolatsioonikate vastab ABYC/USCG isolatsiooninõuetele ning sisaldab märgitähiste jaoks pesasid ning ruumi kahe varukaitselüliti jaoks. Võrreldes teiste Blue Sea toodete, nagu 5035 (6 sõltumatut vooluringi) või 5025 (6 positiivset vooluringi), eristab seda jagudiviga konfiguratsioon maanduse integreerimisega, pakkudes suuremat paindlikkust paigaldusteks, mis vajavad pidevate ja lülitatavate vooluringide segamist ühel asukohal. Kaitselülitid ja märgitähised müüakse eraldi.

« Flexibility and safety for mixed electrical architectures »

The Blue Sea ST Blade 5032B-BSS fuse block is a relevant solution for naval architects and installers facing the increasing complexity of onboard electrical systems. Its split-bus functionality, allowing 24-hour circuits and switched circuits to coexist within a single compact unit, significantly simplifies wiring and maintenance. This configuration is particularly beneficial for cruising sailboats and small motor yachts where space is often limited and clear separation between safety equipment (smoke detectors, bilge alarms) and comfort equipment (radio, cabin lighting) is critical.

The integration of a ground connection on the negative bus enhances safety and compliance with ABYC standards, a key point for long-term reliability. During installation, it is crucial to adhere to the recommended wire sizes (4-6 AWG for the main power feed, 10-16 AWG for branch circuits) and specified torque values to ensure connection integrity. The space for labels and spare fuses under the cover is a practical detail that facilitates quick troubleshooting at sea. While capable of handling a total of 100A, it is important not to exceed 80A per load group to maintain the system's nominal performance. This model is ideal for streamlining secondary electrical panels or extending existing installations without overloading the main panel.
