BOJACK 4-Way ANM Mega Fuse Holder (Pack of 1) - 40–500A, Bolt-On PBT Housing for 12V/24V

BOJACK ANM-B4 4-Way Mega Fuse Holder is a bolt-on fuse base that accepts one to four ANM mega fuses (40–500A) for reliable short-circuit and overload protection in 12V and 24V DC systems.

This heavy-duty fuse holder is built with a durable P.B.T. shell and high-conductivity terminals to resist corrosion, reduce aging, and deliver stable electrical connections up to 32V. Designed for installation on battery cables, converters, inverters, and charge-regulator circuits, the ANM-B4 consolidates multiple large-format DC fuses into a single, serviceable block. The unit ships without fuses, allowing you to select the exact ANM-rated amperage needed for your application.

How does the BOJACK 4-way mega fuse holder protect my electrical system?

The ANM-B4 provides a centralized point for DC mega fuses so overloads and short circuits are interrupted close to the battery or power source. By keeping fuses in a robust, bolt-on housing you reduce the risk of loose terminals and stray arcing under high-current conditions. The P.B.T. body also withstands heat and chemicals better than basic plastics, extending service life.

• Holds one to four ANM mega fuses (40–500A) for tailored protection
• Interrupts faults near the power source for safer circuits
• High-conductivity terminals minimize voltage drop at high currents
• Durable P.B.T. shell resists corrosion and aging

What voltages and fuse types are compatible with this holder?

The BOJACK ANM-B4 is engineered for DC systems up to 32 volts, making it suitable for both 12V and 24V vehicle and marine electrical setups. It accepts ANM-style mega fuses in ampere ratings from 40A to 500A, giving flexibility to match fuses to individual circuit protection needs. Note that the product is the holder only — fuses are purchased separately.

• Rated voltage: up to 32V DC
• Compatible fuse type: ANM DC mega fuses
• Available fuse amperages: 40A through 500A (not included)
• Works in 12V and 24V electrical systems

How easy is it to install and service the ANM-B4 fuse holder?

Installation is straightforward: bolt the holder to a chassis or mounting plate, secure battery and load cables to the heavy-duty terminals, then insert the chosen ANM fuses. The bolt-on design allows quick inspection and replacement of fuses without disturbing other wiring. Clear terminal layout reduces wiring errors during installation or maintenance.

• Bolt-on mounting for secure attachment to chassis or panels
• Accessible terminal posts for large battery cables and lugs
• Removable fuses for fast servicing and replacement
• Designed to reduce wiring mistakes with logical layout

Where is this fuse holder typically used and what environments can it handle?

The ANM-B4 is common in automotive, marine, RV, and industrial power systems where high charging or starting currents require mega fuses. It suits applications such as inverters, battery banks, alternator circuits, LED power runs, and motor-start protection. The materials and terminal design are chosen to hold up under vibration and exposure typical in transportation and production settings.

• Ideal for battery cables to converters, inverters, and regulator outputs
• Used in cars, trucks, boats, RVs, and industrial equipment
• Built to withstand vibration and high-current cycles
• Useful for protecting LED circuits, motors, and power distribution

Who is this for? The BOJACK ANM-B4 4-way mega fuse holder is for installers, electricians, vehicle and boat owners, and equipment builders who need a rugged, flexible fuse block for high-current DC systems. It suits anyone who wants to centralize protection, simplify maintenance, and use industry-standard ANM fuses rated 40–500A. Buy the holder when you want a durable, serviceable mounting point for large DC fuses — select the specific ANM fuse amperages separately to match each protected circuit.
