Detailed description

Skirtas sudėtingoms laivų elektros sistemoms, ST Blade tipo saugiklių blokas su padalintu bendraašiu Blue Sea 5032B-BSS leidžia diferencijuotai valdyti grandines. Jis leidžia sujungti tą pačią bloko vietą šešias nuolatinės srovės (24 valandas) ir šešias jungiamasias grandines, optimizuojant laive kabelių organizavimą. Ši sistema panaikina poreikį naudoti du atskirus blokus nuolatiniam ir valdytam maitinimui, palengvindama esminių įrenginių, tokių kaip siurbliai ir navigacijos sistemos, integravimą.

Galimybės ir techninės specifikacijos

Modelis 5032B-BSS pritaikytas 32V nuolatinei srovei, su 30A srove kiekvienai atskirai grandinei ir 100A bendrai srovei (neviršijant 80A kiekvienai apkrovos grupei). Naudoja ATO® arba ATC® tipo saugiklius, kurie yra plačiai prieinami. Jungtys užtikrinamos #8-32 varžtais su spyruoklinėmis plokštelėmis atšakų grandinėms, priimančiomis 10-16 AWG (6-15 mm²) laidus. Pagrindinis maitinimas jungiamas per #10-32 varžtus, skirti 4-6 AWG (25-16 mm²) laidams, užsukamus nerūdijančio plieno kontrafiliais. Rekomenduojamas sukimo momentas yra 2,71 N·m (24 in-lb) #10 varžtams ir 2,03 N·m (18 in-lb) #8 varžtams.

Konstrukcija ir integracija

Šis saugiklių blokas turi padalintą bendraašį ir varinius alavuotus saugiklių lizdus, užtikrinančius laidumą ir korozijos atsparumą jūrinėje aplinkoje. Skyriklio dangtis atitinka ABYC/USCG izoliacijos reikalavimus, turi etikečių laikmenas bei vietą dviems atsarginėms saugiklių poroms. Palyginus su kitais Blue Sea modeliais, pavyzdžiui, 5035 (6 nepriklausomos grandinės) ar 5025 (6 teigiamosios grandinės), 5032B-BSS išsiskiria padalinto bendraašio konfigūracija su įžemėjimo prijungimu, suteikiančia didesnį lankstumą įrenginiams, reikalaujantiems nuolatinių ir jungiamųjų grandinių vienoje vietoje. Saugikliai ir etiketės parduodami atskirai.

« 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 growing complexity of onboard electrical systems. Its split-bus feature, allowing 24-hour circuits and switched circuits to coexist within a single compact unit, significantly simplifies wiring and maintenance. This configuration is particularly advantageous for cruising sailboats and small motor yachts where space is often limited and a clear distinction between safety equipment (smoke detectors, bilge alarms) and comfort equipment (radio, cabin lighting) is critical.

Integrating 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 main power, 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.

What is a Blue Sea ST Blade split-bus fuse block?

A Blue Sea ST Blade split-bus fuse block is designed to handle both continuously powered circuits (24 hours) and switched circuits on a single block. This allows for optimized wiring organization on board, avoiding the use of two separate blocks for these two types of power supply.

How many circuits does this fuse block support?

This fuse block supports a total of 12 circuits. It is divided into two isolated groups of six circuits each, allowing separation of 24-hour circuits from switched circuits.

What types of fuses are compatible with this fuse block?

This fuse block is compatible with ATO® or ATC® type fuses, which are commonly available fuse types.

What is the maximum current per individual circuit?

Each individual circuit in this fuse block can handle a maximum current of 30 amperes (30A).

What is the maximum total current the fuse block can support?

The fuse block can support a maximum total current of 100 amperes (100A). It is important to note that the current must not exceed 80A per load group (the two groups of six circuits).

What is the maximum operating voltage of this fuse block?

The maximum operating voltage for this fuse block is 32V DC.

What materials are the fuse buses and clips made of?

Fuse buses and clips are made of tinned copper. This material ensures excellent electrical conductivity and superior resistance to corrosion, which is particularly important in a marine environment.

Is the fuse block supplied with a protective cover?

Yes, the fuse block is supplied with a transparent insulating cover. This cover meets ABYC/USCG insulation requirements for enhanced safety.

No, fuses are not included with the purchase of the fuse block and must be purchased separately.

Does the fuse block cover offer additional features?

Yes, the transparent cover is designed with label holders to easily identify each circuit, and it also includes storage space for two spare fuses.

Does this fuse block include a negative bus for ground?

Yes, this fuse block is equipped with a negative bus featuring a #10-32 stud for ground connection.

What wire sizes are recommended for the main power supply of the unit?

For the main positive power supply, use 4 to 6 AWG (25-16 mm²) wires. Connections are made via #10-32 studs.

What are the recommended wire sizes for branch circuits?

For individual branch circuits, use 10 to 16 AWG (6-15 mm²) wires. Connections are made via #8-32 screw terminals.

What is the recommended torque for the main power studs?
