Practical Applications of ANL Laminated Fuses (40A–1000A) for EV, Marine, ESS, and Industrial Systems

Introduction

In high-power systems such as electric vehicles (EVs), marine vessels, solar + energy storage systems (ESS), and industrial automation, ensuring safe and reliable current protection is crucial. Overloads or short circuits in these environments can damage batteries, converters, or motor drives, leading to costly downtime.

Photo-Top Technologies offers the ANL Glass Laminated Fuse series (40A–1000A), designed to withstand up to 6000A breaking force and operate across 32V / 48V / 72V / 125V DC systems.

Key Technical Highlights

• Wide Current Range: 40A to 1000A for low, medium, and ultra-high current protection.

• High Safety Margin: The 6000A breaking force ensures reliable protection and prevents damage even at the tensile strength limit of the fuse casing.

• Versatile Voltage Ratings: Covers 32V / 48V / 72V / 125V DC – suitable for EVs, ESS, and marine applications.

• Durable Construction: Glass laminated housing with tin-plated copper terminals ensures long-lasting conductivity.

• Easy Identification: Avocado green color coding simplifies installation and maintenance.
  

Practical Applications and Case Studies

🚗 Electric Vehicles & Heavy-Duty Transport

ANL Laminated Fuses are widely used in EV battery and drive protection:

• EV traction battery packs (main DC bus)

• High-power inverters and DC-DC converters

• DC fast charging input circuits

• Electric buses & trucks (400A–1000A)

• Automotive aftermarket audio upgrades (100A–300A)

Case Example: A 400kW electric bus integrates an 800A laminated ANL fuse to protect its traction battery pack from short-circuit risks during acceleration and regenerative braking.

🌊 Marine & Offshore Power Systems

In salt-rich and moisture-heavy environments, laminated ANL fuses ensure safe DC distribution:

• Yacht and commercial vessel house battery banks

• Marine propulsion motors (72V DC and above)

• Deck equipment such as winches and hydraulic lifts

• Navigation and communication systems (Radar, GPS, Radio)

Case Example: A 72V DC marine propulsion system employs a 500A ANL fuse to safeguard against short circuits caused by saltwater exposure.

🔋 Solar and Energy Storage Systems (ESS)

Solar and ESS installations require robust high-current fuses to protect DC buses and racks:

• PV inverters (DC input protection)

• Battery energy storage racks (up to 1MWh systems)

• DC combiner boxes in solar farms

• Off-grid solar power units

Case Example: A commercial solar ESS integrates 1000A laminated ANL fuses across its battery racks, ensuring that a single cell failure does not cascade into full system damage.

⚙️ Industrial Automation & Heavy Equipment

ANL Laminated Fuses provide reliable circuit protection in industrial and material-handling systems:

• Electric forklifts (150A–300A)

• Hydraulic lifting platforms and tail lifts

• Motor controllers in automated production lines

• Construction and mining equipment with hybrid DC systems

Case Example: An electric forklift fleet uses 200A ANL laminated fuses to protect DC motor drives, reducing equipment downtime and repair costs.
