The ABB 1SFA899311R3280 is the PSTP-2280/18 thyristor module, a power semiconductor assembly designed as a replacement component for the PSTX series of softstarters. It is classified under the softstarter product class and carries the technical designation PSTP-2280/18.
This part is officially classified as Obsolete by the manufacturer. That means ABB no longer produces it, and no direct factory order is possible. The evidence does not list an official successor order code. Verify the fit with the specific PSTX softstarter model in your panel. The PSTP-2280/18 is a thyristor module, so the replacement must match the voltage and current rating of the original softstarter design.
The module complies with the EU RoHS Directive 2011/65/EU and Amendment 2015/863, so it meets the substance restrictions for lead, mercury, cadmium, and other hazardous materials. It is classified as a Business-to-Business product and falls outside the scope of the WEEE Directive.
