**Please note: Product may differ from image illustration depending on availability.**
The function of a fuse holder is to integrate fuses safely in electrical circuits, ensure a robust current path (voltage does not creep to other components) and provide a method to replace fuses once they manage over current events as intended.
Battery Disconnect switch for DC application.

Additional Information
DC 3P Battery Disconnect Switch 48VDC
Fuses are an integral and essential component in most electrical installations, and they play a vital safety role. The ensure that any excessive current traveling through the wire that could damage the system does not reach critical equipment.
You would need a fuse between the battery and the inverter. This protects the wire and the inverter from overload, potential damage, and fire. Depending on the size inverter you have, you will require different fuses, like 12V, 24V, and 48V inverters would require different size fuses.
To get a better understanding of why you would need a fuse between a battery and inverter, we need to understand the following:
- What function fuses perform between the battery and inverter
- How to determine what size fuse you would need for your inverter
- What happens to the inverter when a fuse blows
Understanding how and why fuses work and why they should always be installed between the battery and the inverter regardless of the inverter size will give you the information you need to ensure your inverter system is protected.
