Fuse Blocks, Fuses & Circuit Breakers

A fuse interrupts excessive current (blows) so that further damage by overheating or fire is prevented. Wiring regulations often define a maximum fuse current rating for particular circuits. Overcurrent protection devices are essential in electrical systems to limit threats to human life and property damage.

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation.

Q. How do fuses and circuit breakers differ?

A. Fuses are thermal devices that open the circuit by utilizing a “fusible link” that melts at a known amperage in a known length of time. Circuit breakers can be either thermal or magnetic devices or a combination of the two.

Blue Sea Safety Hub Fuse Blocks

Blue Sea SafetyHub 100 Fuse Block

aThe Blue Sea Systems SafetyHub 100 is an ignition-protected fuse block with an integrated connecting plug. It consolidates 1A - 200A fuses, and can be wired directly to the battery (for unswitched fuse protection) or after the battery switch (for switched fuse protection).

Blue Sea SafetyHub 150 Fuse Block

The SafetyHub 150 consolidates ignition protected, high amperage and 24 hour circuit protection into one place near the battery while also providing circuit protection for the 360 Panel feed wire. The 360 Panel provides circuit protection for all medium amperage loads and the ST Blade Fuse Block protects the electronics, as these devices are switched on the device. This example minimizes panel space and consolidates circuit protection to only three places on the boat and achieves a critical safety advantage by ensuring all high amperage cables are protected.

MIDI® Fuse Blocks

Blue Sea AMI® / MIDI® Safety Fuse Block

The AMI®/MIDI® Safety Fuse Block uses AMI®/MIDI® fuses.

This relatively new fuse is extremely economical and compact, and offers a clear window for visible indication of blown condition.

AMI®/MIDI® fuses available through Blue Sea Systems have a 5000A interrupting capacity, making them suitable for both main and branch circuit protection.

Both Safety Fuse Blocks carry on the important features of the SafetyHub family. Ignition protection is the core feature of these products. Using ignition protected devices where required is essential for safety and regulatory compliance, and the SafetyHubs and Safety Fuse Blocks are ignition protected to SAE J1171 and ISO 8846. They are safe for use in engine compartments and other locations on gasoline or diesel vessels where a potential fuel source may be present.
