Authentic High-Current Protection for Indian Vehicles

Ensure your vehicle's electrical system is protected by genuine parts PTT MEGA/AMG fuses. These 400A, 32V time-delay fuses are built to ISO 8820 standards, offering superior performance and durability compared to generic alternatives. Imported directly from authorized US retailers, they guarantee authentic specifications for your car, truck, or boat.

Who Should Use These Fuses & Who Should Look Elsewhere

Ideal for owners of high-performance vehicles, custom audio installations, or boats requiring robust circuit protection for high-amperage accessories like amplifiers, winches, or auxiliary power systems. If your vehicle uses a different fuse type (e.g., glass tube, mini blade) or requires a lower amperage rating, these 400A MEGA/AMG fuses are not suitable. Always match fuse amperage and type to the circuit's requirements and vehicle manufacturer specifications.

How to use

  • Identify Circuit Requirements — Determine the exact amperage rating and fuse type (MEGA/AMG, time-delay) required for the circuit you need to protect. Consult your vehicle's manual or the accessory manufacturer's specifications to avoid using an incorrect fuse.
  • Prepare Fuse Holder/Bus Bar — Ensure the fuse holder or bus bar is clean and compatible with M8 (5/16") stud-down fuses. If replacing an existing fuse, carefully remove the old one. Note the required mounting torque specifications (8-14 Nm for M8).
  • Install the Fuse — Place the new parts PTT 400A fuse onto the M8 studs. Secure it firmly using appropriate nuts, tightening to the specified torque (8-14 Nm) to ensure a solid electrical connection. Do not overtighten.
  • Test the Circuit — Restore power to the circuit and test the connected accessory or system. The time-delay function should allow for normal startup surges, while the fuse remains ready to protect against sustained overcurrents.

All customs duties and GST are included in the price, and your order is shipped via ExpressBox with tracking for secure delivery across India.
What fuse type does this holder accept?
This is a MEGA/AMG type fuse, designed for high-current automotive and marine applications. It features a time-delay (slow blow) function and requires bolt-down M8 (5/16") stud mounting. Ensure your circuit's fuse holder or bus bar is compatible with this specific fuse type and amperage rating.
Can I use this fuse holder on a 12V car or a marine setup?
Yes, these parts PTT fuses are rated for 32V DC systems and are compatible with both 12V and 32V DC automotive and marine applications. Their robust construction and operating temperature range make them suitable for demanding environments like engine bays or boat electrical systems.
What are the benefits of time-delay fuses?
Time-delay fuses, also known as slow-blow fuses, are designed to handle temporary current surges that occur when certain devices (like motors or amplifiers) start up. They allow these brief surges without blowing, while still providing protection against sustained overcurrents or short circuits.
Are these fuses safe for high-amperage systems?
Yes, these 400 Amp fuses are specifically designed for high-amperage circuits. They have a high interrupting rating of 2000A at 32VDC, meaning they can safely interrupt very large fault currents without exploding. Always ensure the fuse amperage matches the circuit's protection needs.
What is the best fuse for car amplifiers?
For car amplifiers, a time-delay (slow-blow) fuse like this parts PTT MEGA/AMG 400A fuse is often recommended. It can handle the initial current surge when the amplifier powers on without blowing, while still protecting the system from dangerous overloads. Ensure the amperage rating matches your amplifier's requirements.
How to choose the right fuse?
Select a fuse that matches the amperage rating of the circuit it's protecting, and ensure it's the correct type (e.g., MEGA/AMG, ATO, glass tube) and voltage rating (32V DC for automotive/marine). Time-delay fuses are best for circuits with high inrush currents. Always consult your vehicle's manual or the accessory manufacturer's specifications.
Do these fuses come with a warranty?
CrowCrowCrow offers a 14-Day Smile Guarantee for any wrong or damaged items received. For manufacturing defects, the original USA manufacturer's warranty applies. We ensure you receive authentic, factory-sealed products sourced directly from authorized US retailers.
