HUDSON EVU8.0-150-B High-Voltage DC Main Fuse

The HUDSON EVU8.0-150-B High-Voltage DC Main Fuse is a heavy-duty, fast-acting circuit protection device engineered specifically for the main powertrains of modern electric vehicles (EVs) and heavy renewable energy systems. Rated for 150 Amps at 800 Volts DC, this large-format ceramic tube fuse operates under the "gEV" class, meaning it is designed as a full-range general-purpose fuse optimized specifically for the unique demands of electric vehicle 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: EVU8.0-150-B

• Current Rating: 150 Amps (150A)

• 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:

• Main Drivetrain Protection – Specifically designed for 800V EV architectures, this 150A fuse easily handles the continuous current draw of EV traction motors, inverters, and high-power DC fast charging loops.

• Immense 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 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 smothering 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 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 road vibration.

Ideal For:

• Main traction battery disconnects and Service Disconnects (MSD) in Electric Vehicles

• Protecting EV motor controllers and medium-to-large drive inverters

• High-Voltage Power Distribution Units (HV-PDU) in commercial EVs and retrofits

• Megawatt-scale Solar (PV) array main feeds

• Grid-scale Battery Energy Storage Systems (BESS)

• DC Fast Charging (DCFC) station main infrastructure
