The Alvolta 150A Battery Terminal Fuse (MRBF) is an ignition-protected, marine-rated battery fuse that bolts straight onto the positive battery terminal. Fusing at the battery protects the whole cable run from the very first millimetre — the correct approach for any 12V, 24V or 48V system carrying serious current.
Features
- 150A rating with fast, reliable interrupt on overcurrent and short circuit
- Ignition protected — safe for battery compartments and engine bays
- Suitable for systems up to 58V DC (12V, 24V and 48V)
- Secure bolt-in connection, no crimping required
- Corrosion-resistant connector blades for marine and coastal use
- Blown-fuse indicator window for instant visual diagnosis
- Colour-coded by amperage so the rating is obvious at a glance
- Compact footprint — fits tight battery boxes and under-bonnet installs
Where to use it
MRBF terminal fuses connect as close as possible to the positive terminal of a battery, protecting the wiring from overcurrent and short circuits. A 150A rating suits mid-size inverter feeds, 40A–50A DC-DC charger circuits, lithium house banks and heavier dual-battery links. It is typically paired with cable in the 25mm² range — always size the fuse to protect the cable, not the load.
