The ABB 1SFA899005R3020 is a PSFU-450 semiconductor fuse rated for 450 A continuous current in in-line connection. Per the datasheet (1SFC132005M0201), this is a high-speed fuse designed to protect power semiconductors — thyristors, diodes, IGBT modules — against short-circuit faults where standard industrial fuses would let through too much energy.
Lifecycle stage is current (active). No end-of-life notice or last-time-buy date.
WEEE classified as Category 5 — Small Equipment (external dimension ≤ 50 cm), B2B channel. Conflict Minerals Reporting Template (CMRT) is available under document 9AKK108467A5658. The instruction manual is 1SFC388004-89; the technical datasheet is 1SFC132005M0201.
