BOJACK 4-Way ANM Mega Fuse Holder (ANM-B4) — Bolt-On PBT Housing, 40–500A, 12V/24V

BOJACK 4-Way AMG Mega Fuse Holder (ANM-B4) is a durable bolt-on fuse block that accepts one to four ANM mega fuses (40–500A) for 12V and 24V DC systems up to 32V.

This heavy-duty ANM-B4 fuse holder is built for high-current circuits where reliable overcurrent protection and straightforward installation matter. Constructed with a PBT shell and rugged metal terminals, it resists corrosion and aging while providing a clear, serviceable holder for mega fuses used on battery cables, inverters, converters, and high-current accessories. The unit ships as a single 4-way holder; fuses are sold separately.

How does the ANM-B4 protect my electrical system?

The BOJACK 4-Way fuse holder secures ANM-type mega fuses that interrupt high-current faults, helping isolate short circuits or overloads. By centralizing up to four fuses in a bolt-on block, it makes troubleshooting and replacement quicker while keeping connections mechanically strong.

• Accepts ANM 40–500A DC fuses rated to 32V
• Protects battery cables, inverters, and charge regulators
• Durable PBT housing resists corrosion and aging
• Bolt-on design provides solid mechanical and electrical connection

What electrical systems and fuse sizes are compatible?

This holder supports both 12V and 24V electrical systems commonly found in vehicles, marine craft, and solar or backup power setups. It accommodates ANM mega fuses across a broad amp range, giving flexibility for main power feeds or high-current accessory circuits.

• Fuse type: ANM DC mega fuses
• Available fuse ratings: 40A through 500A
• Maximum voltage: 32 volts DC
• Suitable for 12V and 24V installations

How do I install and maintain the BOJACK 4-Way fuse holder?

Installation is straightforward: bolt the holder to a grounded panel or chassis, attach battery and load cables to the terminals, and insert properly rated ANM fuses (not included). Periodic inspection of terminals and torque checks will keep connections reliable, and the PBT shell simplifies cleaning and visual inspection.

• Bolt-on mounting for secure chassis attachment
• Use correct gauge cable and terminal hardware for amperage
• Check terminal tightness and corrosion periodically
• Replace fuses with matching ANM ratings only

Can this holder be used with inverters or charge controllers?

Yes — the ANM-B4 is suitable where high charging currents or inverter feeds require fused protection near the battery. Choose fuses sized for the device's maximum sustained current and short-circuit characteristics for safe operation.

• Ideal for inverters, converters, and high-current charge regulators
• Place the holder close to the battery for optimal protection
• Match fuse amperage to device and cable specifications

Who is this for? The BOJACK 4-Way AMG Mega Fuse Holder (ANM-B4) is aimed at installers, automotive and marine electricians, DIY vehicle-upfitters, and system integrators who need a compact, durable multi-fuse mount for high-current DC circuits. If you wire or protect 12V/24V battery systems, inverters, or heavy accessories and want an organized, serviceable solution for up to four ANM mega fuses, this holder offers a dependable, corrosion-resistant component to simplify maintenance and improve circuit safety.
