FAQ Frequently Asked Questions
Q
What is the difference between the AEP, EFT, and AEY series ESS fuses?
The AEP series is designed for 32/65 Vdc applications with rated currents from 20A to 200A and a breaking capacity up to 1.5kA. The EFT series supports higher voltages (63–200 Vdc) with rated currents from 100A to 500A and a much higher breaking capacity of 20kA, making it suitable for more demanding industrial applications. The AEY series operates at 70 Vdc with rated currents from 10A to 500A and a breaking capacity of 2.5kA.
Q
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, making them suitable for harsh industrial environments with extreme temperature variations.
Q
Which fuse holders are compatible with the AEP and AEY series fuses?
For the AEP series (M5/M6 bolt installation), the recommended fuse holder is BHR030-15-M5. For the AEY series (M8 bolt installation), compatible fuse holders include BHR059-25-M8, BHR051-25-M8, and BHR050-25-M8.
Q
What are the main applications for these ESS fuse series?
All three series — AEP, EFT, and AEY — are engineered for Industrial Energy Storage Systems (ESS) and Power Distribution Protection. They are specifically designed to provide reliable short-circuit protection and reliable clearing of DC fault currents in demanding industrial environments.
Q
What installation method is used for the AEP series ESS fuse?
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 to ensure a secure and reliable connection.
Q
Why is the EFT series suitable for high-demand industrial ESS applications?
The EFT series stands out due to its ceramic main body construction, ultra-compact size with high power density, low watt losses, and an exceptionally high breaking capacity of up to 20kA. These features make it ideal for high-demand industrial ESS and power distribution environments where reliable short-circuit protection is critical.
