Detailed description

Namijenjen složenim električnim instalacijama na brodu, blok osigurača ST Blade s podijeljenom sabirnicom tvrtke Blue Sea 5032B-BSS omogućuje diferencirano upravljanje krugovima. Omogućuje kombiniranje šest stalno napajanih (24 sata) i šest preklopnih krugova na istom bloku, optimizirajući tako organizaciju ožičenja na brodu. Taj sustav eliminira potrebu za dva odvojena bloka za stalne i kontrolirane napajanja, olakšavajući integraciju ključne opreme kao što su crpke za palubu i navigacijski sustavi.

Mogućnosti i tehničke specifikacije

Model 5032B-BSS dimenzioniran je za maksimalni napon od 32V istosmjernog napona, s kapacitetom od 30A po pojedinom krugu i ukupnom strujom od 100A (bez prekoračenja od 80A po grupi opterećenja). Koristi osigurače tipa ATO® ili ATC®, koji su lako dostupni. Spojevi se izvode vijcima #8-32 s pričvrsnim podloškama za odvojne krugove, prihvaćajući žice promjera 10 do 16 AWG (6-15 mm²). Glavno napajanje spaja se preko vijaka #10-32, prikladnih za žice od 4 do 6 AWG (25-16 mm²), osigurano maticama s podloškom od nehrđajućeg čelika. Preporučeni moment zatezanja je 2,71 N·m (24 in-lb) za vijke #10 i 2,03 N·m (18 in-lb) za vijke #8.

Konstrukcija i integracija

Ovaj blok osigurača ima sabirnice i držače osigurača od pocinčanog bakra, osiguravajući vodljivost i otpornost na koroziju pogodnu za morske uvjete. Prozirni izolacijski poklopac zadovoljava zahtjeve ABYC/USCG izolacije i uključuje prostor za oznake kao i mjesto za pohranu dvaju rezervnih osigurača. U usporedbi s drugim proizvodima iz Blue Sea serije, kao što su blok 5035 (6 neovisnih krugova) ili 5025 (6 pozitivnih krugova), 5032B-BSS se ističe konfiguracijom s podijeljenom sabirnicom s integriranim uzemljenjem, nudeći veću fleksibilnost za instalacije koje zahtijevaju kombinaciju stalnih i preklopnih krugova na jednoj lokaciji. Osigurači i oznake se prodaju zasebno.

« 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 the same 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 respect 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. Although 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 expanding 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 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.

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 that 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 blocks and clips made of?

The fuse blocks and clips are made of tinned copper. This material provides excellent electrical conductivity and superior corrosion resistance, particularly important in a marine environment.
