BS 5194 - 3 independent circuits compact at the battery terminal
The Blue Sea BS 5194 MRBF fuse block is a masterpiece of space efficiency. It allows for three completely independent circuits to be fused directly at a single power source. Perfect for separately but centrally fusing a charger, inverter, and bow thruster at the main battery, for example.
Ignition protection and superior flexibility
Thanks to the separate feeds, this model offers maximum electrical flexibility. Despite the triple function, the module remains completely ignition-protected (ISO 8846) and extremely compact. The included insulating cap protects all connections against short circuits in accordance with regulations (ABYC/USCG).
Key benefits at a glance:
- Independent circuits: 3 separate MRBF fuses without a common busbar.
- Enormous power: Up to 300 amperes possible per circuit.
- Compact layout: Saves significant space and cable lugs.
- Ignition-protected: Safe for use in engine rooms (ISO 8846).
- Corrosion protection: Robust, tinned copper studs.
