HUDSON EVU8.0-100-B High-Voltage DC Fuse

The HUDSON EVU8.0-100-B High-Voltage DC Fuse is a fast-acting, heavy-duty circuit protection device engineered specifically for the powertrains and high-draw auxiliary systems of modern electric vehicles (EVs) and renewable energy platforms. Rated for 100 Amps at 800 Volts DC, this ceramic tube fuse operates under the "gEV" class, meaning it is designed as a full-range general-purpose fuse optimized for the unique power demands and safety requirements of EV architectures.

Key Specifications:

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

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

• Manufacturer: HUDSON

• Model / Part Number: EVU8.0-100-B

• Current Rating: 100 Amps (100A)

• 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:

• High-Voltage EV Protection – Specifically designed for 800V EV architectures, this 100A fuse is perfect for protecting medium-to-large high-voltage sub-systems, such as high-output DC-DC converters, large PTC cabin heaters, and auxiliary power distribution loops.

• Immense 60kA Breaking Capacity – In the event of a catastrophic dead-short, this fuse safely absorbs and extinguishes fault currents up to 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 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:

• Protecting high-draw auxiliary EV circuits (DC-DC converters, heavy-duty PTC heaters, power steering pumps)

• High-Voltage Power Distribution Units (HV-PDU) in passenger EVs and custom hybrid conversions

• Solar array (PV) combiner boxes and string protection

• Battery Energy Storage Systems (BESS)

• DC Fast Charging (DCFC) station sub-circuits
