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 up to 1.5kA. The EFT series covers a wider voltage range (63–200 Vdc) with rated currents from 100A to 500A and a higher breaking capacity of 20kA. The AEY series is designed for 70 Vdc applications 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 Industrial Energy Storage Systems (ESS) and Power Distribution Protection applications, providing reliable short-circuit protection in demanding environments.
Q What is the operating temperature range for these fuses?
The AEP and AEY series are both rated for an operating temperature range of -40°C to 125°C, making them suitable for harsh industrial environments. The EFT series is also built to withstand extreme conditions using a ceramic main body for enhanced durability.
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. Please consult the product specifications for EFT series holder recommendations.
Q What installation methods and torque specifications apply to these fuses?
The AEP series uses M5 or M6 bolt installation, both requiring a torque of 2.5±0.5 N·m. The AEY series uses M8 bolts with a specified torque of 12 N·m. Always follow the recommended torque values to ensure a secure and reliable connection.
Q Why is the EFT series suitable for high-power ESS applications?
The EFT series features a high breaking capacity of up to 20kA, a ceramic main body for thermal stability, ultra-compact size for high power density, and low watt losses — making it ideal for high-power industrial ESS and power distribution systems requiring robust short-circuit protection.
