Description
For high-current applications in automotive and DC power installations, the HUMSER 300 Amp Mega Fuse is a reliable electrical safety measure. The heat-resistant housing withstands severe vibration, shock, and thermal stress, and the bolt-mounted construction ensures safe, low-resistance connections. In harsh settings like engine bays, power blocks, or battery compartments, it increases safety and longevity by protecting vital circuits like batteries, alternators, and starters from overloads and short circuits. It is designed for continuous 300 Amp operation.
Features
:- With a continuous current rating of 300 Amps, it can withstand difficult high-load situations without failing.
- For optimum performance, bolt-mounted terminals offer quick, reliable mechanical and electrical connections with low resistance.
- Low voltage drop and effective power flow are guaranteed by heavy-duty construction with high-conductivity materials.
- When used for extended periods of time, heat-resistant housing resists melting since it can tolerate high temperatures.
- Perfect for mobile applications like off-road vehicles or maritime equipment, these shock- and vibration-resistant materials are perfect.
- Quick activation of short-circuit and over-current protection protects components and wiring.
- Robust design that can withstand extreme conditions like dampness, dust, and mechanical strain.
Applications
:- Protection of the primary power system and automobile batteries
- Automobile and truck high-load 12V and 24V DC circuits
- Protections for starters, alternators, and principal feed
- Motorhomes, buses, RVs, campers, and off-road vehicles
- DC power systems for boats and marines
- Installing high-wattage devices and audio amplifiers
- Battery storage systems, inverters, and solar panels
- Industrial DC equipment and heavy machinery
Usage
:- Choose a fuse rating (300A for this model) that corresponds to the highest continuous current in your circuit.
- Attach with bolts to a stable surface in distribution blocks, engine bays, or battery compartments.
- For a low-resistance contact, use the terminals that are provided to connect inline with a positive cable.
- To securely handle 300A loads, make sure the wire gauge is appropriate (for example, 0/1 AWG or bigger).
- Before fully powering up after installation, check the circuit continuity.
- When performing maintenance, always disconnect the power source first and replace if blown.
