Frequently Asked Questions
Q What is the difference between the AEP, EFT, and AEY series ESS fuses?
The AEP series supports 32/65 Vdc with rated currents from 20A to 200A and a breaking capacity 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, featuring a ceramic main body. The AEY series is rated at 70 Vdc with 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, providing reliable short circuit protection in demanding industrial environments.
Q What operating temperature range do these fuses support?
The AEP and AEY series both support an operating temperature range of -40°C to 125°C, making them suitable for harsh industrial and outdoor environments. The EFT series is also built to industrial standards for wide temperature operation.
Q Which fuse holders are recommended for these products?
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. Always refer to the product datasheet for your specific model before selecting a fuse holder.
Q How are these ESS fuses installed?
The AEP series uses M5 or M6 bolt installation with a torque specification of 2.5±0.5 N·m for both bolt sizes. The AEY series uses M8 bolts with a torque of 12 N·m. Proper torque values should always be followed to ensure safe and reliable electrical connections.
Q Why is a high breaking capacity important in ESS fuses?
A high breaking capacity ensures the fuse can safely interrupt large fault currents without damage or arc flash hazards. The EFT series, with a breaking capacity of up to 20kA, is especially suited for high-power ESS installations where fault currents can be very large, protecting both equipment and personnel.
