This is an original DC input fuse protection board for ABB Aurora / Power-One solar inverters rated at 10.0kW to 12.5kW. The board provides critical overcurrent and short-circuit protection for the DC input stage, preventing downstream component failure and reducing fire risk.

Manufactured by Power-One, this board is identified as PN: 3683, built on lead-free (Pb-free) green fiberglass PCB, and integrates 6x SIBA 50A 1000V cylindrical fuses, each enclosed in a transparent yellow safety cover.

🔄 Condition: Used, fully inspected and in excellent functional condition.
