HUDSON EVU8.0-250-C High-Voltage DC Main Fuse

The HUDSON EVU8.0-250-C High-Voltage DC Main Fuse is a massive, fast-acting circuit protection device engineered specifically for the main powertrains of modern electric vehicles (EVs) and heavy-duty renewable energy systems. Rated for an immense 250 Amps at 800 Volts DC, this large-format ceramic tube fuse is designed to act as the primary fail-safe between the main high-voltage battery pack and the vehicle's drive inverter, protecting against catastrophic short circuits.

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: EVU8.0-250-C

• Current Rating: 250 Amps (250A)

• 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 architectures, this 250A fuse is built to handle the massive continuous current draw of EV traction motors while maintaining the ability to instantly sever the connection during a fault.

• Immense 60kA Breaking Capacity – In the event of a catastrophic dead-short in a high-capacity battery pack, this fuse can safely absorb and extinguish fault currents up to a staggering 60,000 Amps without the casing rupturing or catching fire.

• Arc-Extinguishing Construction – The thick, high-strength 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 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 massive, thick metal blade terminals with pre-drilled holes. This allows the fuse to be securely bolted directly onto solid copper busbars inside a main High-Voltage Power Distribution Unit (HV-PDU) or battery disconnect box.

Ideal For:

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

• Protecting heavy-duty EV motor controllers and drive inverters

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

• Megawatt-scale Solar (PV) array main feeds

• Grid-scale Battery Energy Storage Systems (BESS)

• DC Fast Charging station main infrastructure
