Detailed description

Namenjen kompleksnim električnim instalacijam na ladjah, vodilna sklopka ST Blade z razdeljenim vodilnikom Blue Sea 5032B-BSS omogoča ločeno upravljanje krogov. Omogoča združevanje šestih krožnih krogov s konstantno napajanje (24 ur) in šestih komutiranih krogov, kar optimira organizacijo kabliranja na krovu. Ta sistem odpravlja potrebo po dveh ločenih sklopkah za potrebe stalnega in nadzorovanega napajanja, kar olajša vgradnjo ključnih oprem, kot so črpalke za vodo in navigacijski sistemi.

Zmožnosti in tehnične specifikacije

Model 5032B-BSS je zasnovan za največjo napetost 32 V enosmerne napetosti, z zmogljivostjo 30 A na posamezni krog in skupno 100 A (pri čemer ne sme presegati 80 A na skupino). Uporablja varovalke tipa ATO® ali ATC®, ki so široko dostopne. Povezave so zagotovljene z vijaki #8-32 z zajemnimi podložkami za odvodne kable, ki sprejemajo vodnike od 10 do 16 AWG (6–15 mm²). Glavno napajanje se povezuje prek vijakov #10-32, prilagojenih za vodnike od 4 do 6 AWG (25–16 mm²), z varnostnimi maticami iz nerjavnega jekla. Priporočeni navor za vijake #10 je 2,71 N·m (24 in-lb), za vijake #8 pa 2,03 N·m (18 in-lb).

Konstrukcija in vgradnja

Ta vodilna sklopka je opremljena z vodilniki in držali varovalk iz pocinčanega bakra, kar zagotavlja primerno prevodnost in odpornost proti koroziji v morskem okolju. Prosojna izolacijska pokrovka ustreza zahtevam ABYC/USCG za izolacijo in vključuje prostora za nalepnice ter prostor za shranjevanje dveh rezervnih varovalk. V primerjavi z drugimi izdelki iz linije Blue Sea, kot sta sklopka 5035 (6 neodvisnih krogov) ali 5025 (6 pozitivnih krogov), se 5032B-BSS odlikuje po konfiguraciji z razdeljenim vodilnikom z vgrajeno ozemljitvijo, kar ponuja večjo fleksibilnost za vgradnjo, ki zahteva mešanico stalnih in komutiranih krogov na enem mestu. Varovalke in nalepnice se prodajajo ločeno.

« 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 functionality, allowing the coexistence of 24-hour circuits and switched circuits 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 where a clear distinction between safety equipment (smoke detectors, bilge alarms) and comfort equipment (radio, cabin lighting) is essential.

The integration of a ground connection on the negative bus enhances safety and compliance with ABYC standards, a critical 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 rapid 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.

Frequently asked questions

Need help? Contact us

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 power types.

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.

Which 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 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?

The fuse buses and clips are made of tinned copper. This material ensures excellent electrical conductivity and superior resistance to corrosion, 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.

Are fuses included with the purchase of the fuse block?

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

Does the fuse block cover provide any 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 feed to the unit?

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

What wire sizes are recommended 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 feed studs?
