The ABB 1SFA899301R1260 is a bypass connector, also referred to as a bypass contactor, designated PSBP-205-1. It is designed for use with PSTX soft starters, providing a bypass path around the soft starter's thyristors once the motor is at full speed, reducing heat dissipation and extending starter life. This component is suitable for the product class of soft starters, meaning it integrates into a PSTX-based motor-starting system to handle continuous full-load current after start-up.
Integration Note for Panel Builders
The PSBP-205-1 mounts directly to the PSTX soft starter frame, forming a mechanical and electrical bypass assembly. No separate DIN-rail footprint is needed; the connector shares the soft starter's enclosure volume. RoHS compliance is confirmed per EU Directive 2011/65/EU and Amendment 2015/863, and the product is classified as Business To Business (B2B) only, not subject to WEEE scope.
