ST Blade 12 shēmu drošinātāju bloks ar negatīvās kopnes un vāku

The Blue Sea ST Blade 5026B-BSS fuse block is an electrical distribution solution designed for marine installations. It protects up to 12 separate circuits using ST Blade-type fuses, providing individual protection for onboard equipment against overcurrent. This model features an integrated negative bus and a protective cover.

This fuse block provides 12 individual protection circuits. Each circuit is independent, allowing protection of a variety of electrical equipment aboard your boat.

The 5026B-BSS fuse block is designed to be used with ST Blade type fuses, also known as ATO or ATC. These are standard fuses, widely available.

Yes, this fuse block includes a negative bus. The main advantage is the significant simplification of the wiring. It provides a common return point for all negative circuits, which reduces cable harness clutter and optimizes DC connection management in your marine installation.

Yes, the ST Blade 5026B-BSS fuse block is supplied with a cover. This cover provides protection against water spray, dust, and accidental contact, contributing to the safety and durability of the installation.

This fuse block is designed to operate with 12V and 24V electrical systems, making it compatible with most marine installations.

Each individual circuit in this fuse block can handle a maximum current of 30 amperes (30A), providing effective protection against overcurrent for the connected device.

Yes, the 5026B-BSS fuse block complies with European Directive 2002/95/EC (RoHS). This means it is manufactured without hazardous substances such as lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE), thus meeting the permitted thresholds.

A fuse block protects electrical circuits and connected equipment from damage caused by overcurrents or short circuits. In case of a problem, only the fuse in the affected circuit blows, cutting power to the faulty device without affecting the rest of the electrical system.

Model 5026B-BSS stands out for its combination of 12 circuits and the integration of a negative bus. This provides superior management capacity for a large number of devices while simplifying wiring compared to models without a negative bus or with fewer circuits (such as the 5025 with 6 circuits or the 5028 without a negative bus).

The weight of this fuse block is approximately 0.34 kilogram (kg).

Yes, this fuse block is specifically designed for marine installations. Its robustness and design, including the protective cover, make it ideal for the demanding environments found on boats.

The 5026B-BSS fuse block is typically mounted using screws. It is recommended to secure it on a flat and stable surface, in an easily accessible location for maintenance and fuse replacement, while being protected from direct elements.

Yes, the wiring is considerably simplified thanks to the design of this block, particularly due to its integrated negative bus. This centralizes all negative connections from the circuits to a single point, reducing the number of wires and installation complexity.

The main positive power feed (typically from the battery or main circuit breaker) connects to a single input terminal block on the unit. The positive outputs for the 12 circuits connect to individual terminals on the block, each protected by a fuse. The integrated negative bus serves as the connection point for all negative returns from the equipment.

When installing on a boat, ensure the unit is mounted in a dry location protected from direct water spray. Use cables with a cross-section suitable for the intended amperage and marine-grade terminals for all connections to ensure good conductivity and corrosion resistance.

Yes, the 5026B-BSS fuse block is fully compatible with 12V or 24V electrical systems, making it versatile for various marine applications.

This block can protect a wide range of marine electrical devices, including:

Navigation systems (GPS, depth sounders, radars)Interior and exterior lightingBilge and livewell pumpsRadios and audio systems12V/24V power outletsFans and other accessories.

Yes, you can and should use fuses of different ratings on the 12 circuits, based on the specific requirements of each connected device. The key is to select a fuse with an amperage slightly higher than the normal consumption of the device, but lower than the maximum amperage the wiring can handle, and not exceeding 30A per circuit.

Yes, ST Blade fuses are the same as standard automotive ATO/ATC fuses. You can therefore use commonly available automotive fuses for this fuse block.
