Frequently Asked Questions
Q What is the difference between the AEP, EFT, and AEY ESS fuse series?
The AEP series operates at 32/65 Vdc with rated currents from 20A to 200A and a breaking capacity of up to 1.5kA. The EFT series covers a wider voltage range (63–200 Vdc) with higher rated currents (100A–500A) and a much higher breaking capacity of 20kA, making it suitable for more demanding fault protection. The AEY series is designed for 70 Vdc systems with rated currents from 40A to 500A and a breaking capacity of 2.5kA.
Q What applications are these ESS fuses designed for?
All three series — AEP, EFT, and AEY — are engineered for use in Industrial Energy Storage Systems (ESS) and Power Distribution Protection. They are ideal for short circuit protection in DC power systems, battery packs, and industrial power distribution equipment.
Q What is the operating temperature range for these fuses?
The AEP and AEY series ESS fuses are rated for an operating temperature range of -40°C to +125°C, ensuring reliable performance in both extreme cold and high-temperature industrial environments.
Q What fuse holders are recommended for these ESS fuses?
For the AEP series, the recommended fuse holder is BHR030-15-M5. For the AEY series, compatible fuse holders include BHR059-25-M8, BHR051-25-M8, and BHR050-25-M8. Using the correct fuse holder ensures safe and reliable installation.
Q What installation method and torque specifications are required for the AEP fuses?
The AEP series uses M5 or M6 bolt installation. The recommended torque for both M5 and M6 bolts is 2.5±0.5 N·m. Proper torque application is important to ensure a secure electrical connection and prevent contact resistance issues.
Q Why does the EFT series feature a ceramic main body?
The ceramic main body of the EFT series provides excellent thermal resistance and mechanical strength, enabling reliable clearing of high DC fault currents up to 20kA. Ceramic construction also contributes to low watt losses and supports the ultra-compact, high power density design of the fuse.
