AHCA/AHC5A/AHCFA High-Voltage Ceramic Tube Fuses

Eaton Electronics AHCA/AHC5A/AHCFA High-Voltage Ceramic Tube Fuses are automotive grade fast-acting performance fuses with a 6.3mm x 32mm (¼” x 1¼”) compact 3AB footprint. These fuses incorporate up to 500V_AC ratings and provide reliable overcurrent protection up to 30A for high-voltage applications. The AHCA/AHC5A/AHCFA high-voltage fuses feature very high interrupting ratings to help safely protect against dangerous high fault currents. These fuses are available in cartridge, axial lead, and PCB terminal mount versions. Typical applications include onboard power conversion (Inverter/OBC/PDU) for xEVs, stationary EV charging stations, single-phase and 3-phase UPS, energy storage, and battery management systems.
