HUDSON EVU8.0-350-C High-Voltage DC Main Fuse

The HUDSON EVU8.0-350-C High-Voltage DC Main Fuse is a massive, fast-acting circuit protection device engineered specifically for the main powertrains of advanced electric vehicles (EVs) and heavy-duty renewable energy systems. Rated for an immense 350 Amps at 800 Volts DC, this large-format ceramic tube fuse operates under the "gEV" class, meaning it is optimized as a full-range general-purpose fuse to handle the extreme power demands of modern high-voltage EV architectures.

Key Specifications:

• Category: Automotive Parts & Accessories / EV High Voltage Components / Fuses & Circuit Breakers

• Product Type: High-Voltage DC EV Main Fuse (Fast-Acting / gEV Class)

• Manufacturer: HUDSON

• Model / Part Number: EVU8.0-350-C

• Current Rating: 350 Amps (350A)

• Maximum Voltage Rating: 800V DC

• Interrupting Rating (Breaking Capacity): 60kA (60,000 Amps)

• Mounting Type: Center-bolted tags / Heavy-duty blade terminals

• Industry Standards: ISO 8820, JASO D622, Q/HSF 907

• Certifications: CE Compliant

• Body Material: High-strength, thermal-resistant ceramic/melamine

Key Features:

• Extreme Drivetrain Protection – Specifically designed for 800V EV architectures, this 350A fuse easily handles the massive continuous current draw of high-performance EV traction motors, heavy commercial drive inverters, and ultra-fast DC charging loops.

• Massive 60kA Breaking Capacity – In the event of a catastrophic dead-short in the high-voltage system, this fuse safely absorbs and extinguishes fault currents up to a massive 60,000 Amps without the outer casing rupturing or catching fire.

• Arc-Extinguishing Construction – The thick white ceramic tube is internally packed with specialized, high-purity silica sand that instantly melts into glass during a blown-fuse event, safely suffocating the violent DC electrical arc.

• Automotive Standard Compliance – Stamped with ISO 8820 and JASO D622 compliance, ensuring it meets strict international requirements for road vehicles and high-voltage electrical safety.

• Vibration-Proof Installation – Features heavy-duty, thick metal blade terminals with pre-drilled holes. This allows the fuse to be securely bolted directly onto solid copper busbars inside a High-Voltage Power Distribution Unit (HV-PDU), preventing it from loosening under heavy road vibration.

Ideal For:

• Main traction battery disconnects and Manual Service Disconnects (MSD) in heavy-duty Electric Vehicles

• Protecting high-output EV motor controllers and large drive inverters

• High-Voltage Power Distribution Units (HV-PDU) in commercial electric trucks, transit buses, and marine applications

• Megawatt-scale Solar (PV) array main feeds

• Grid-scale Battery Energy Storage Systems (BESS)

• High-power DC Fast Charging (DCFC) station main infrastructure
