Frequently Asked Questions
Q1
What is the difference between the AEP, EFT, and AEY series ESS fuses?
The AEP series operates at 32/65 Vdc with rated currents of 20–200A and a breaking capacity of up to 1.5kA, making it suitable for lower-voltage ESS applications. The EFT series supports a wider voltage range (63–200 Vdc) with higher rated currents of 100–500A and a significantly higher breaking capacity of 20kA, ideal for demanding industrial environments. The AEY series is rated at 70 Vdc with currents from 40–500A and a breaking capacity of 2.5kA, offering a mid-range solution for energy storage systems.
Q2
What installation methods are supported by these ESS fuses?
The AEP series uses M5 or M6 bolt installation with a recommended torque of 2.5±0.5 N·m for both bolt sizes. The AEY series uses M8 bolts with a torque requirement of 12 N·m. The EFT series is designed for compact installation environments; please refer to the product datasheet for specific mounting instructions.
Q3
What fuse holders are recommended for these ESS fuse series?
For the AEP series, the recommended fuse holder is the BHR030-15-M5. For the AEY series, compatible fuse holders include BHR059-25-M8, BHR051-25-M8, and BHR050-25-M8. For the EFT series, please consult the product specification sheet or contact our technical team for the appropriate fuse holder recommendations.
Q4
What operating temperature range do these ESS fuses support?
Both the AEP and AEY series ESS fuses are rated for an operating temperature range of -40°C to +125°C, ensuring reliable performance in extreme industrial and outdoor environments. The EFT series is also engineered for high-reliability industrial use; refer to the product datasheet for its specific temperature specifications.
Q5
Are these fuses suitable for short circuit protection in ESS applications?
Yes. All three series — AEP, EFT, and AEY — are specifically engineered for short circuit protection in Industrial ESS (Energy Storage Systems) and Power Distribution applications. The EFT series, in particular, features a high breaking capacity of up to 20kA and reliable clearing of DC fault currents, making it especially well-suited for high-demand short circuit protection scenarios.
Q6
What materials are used in the construction of these ESS fuses?
All series are manufactured using the highest quality materials and tested to the highest industry standards. The EFT series features a ceramic main body, which provides excellent thermal stability and high breaking capacity. The AEP and AEY series are built to ensure low watt losses, ultra-compact size, and high power density for efficient energy storage system integration.
