ABB 3HAC14551-3 05A Capacitor Unit

ABB 3HAC14551-3 Capacitor Unit is a C4-designated capacitor module used in ABB robot systems, specifically documented as the DSQC 620_C4 Capacitor Unit for IRC5 controllers. The part number 3HAC14551-3 identifies the capacitor module itself, and industry catalogs consistently reference this model as the C4 capacitor unit within ABB’s DSQC 620 controller family. A closely related variant, 3HAC14551-3/06A, appears in several distributor listings, indicating minor revisions within the same capacitor-unit family while preserving compatibility with the DSQC620_C4 configuration. The capacitor unit is designed to fit in the DSQC620_C4 slot used in ABB IRB/IRC5 robot configurations, serving as the dedicated capacitor module within the robot’s control electronics. For technicians replacing worn or failed components, locating the exact 3HAC14551-3 part ensures alignment with ABB spare-part catalogs and official manuals that reference DSQC620_C4 capacitor units. In practice, buyers should verify compatibility with their specific ABB robot model (for example IRC5-based IRB systems) and the DSQC620_C4 configuration when ordering, to ensure the capacitor unit will integrate with the existing DSQC620_C4 harnessing and mounting provisions. The 3HAC14551-3 designation thus uniquely identifies this capacitor module within ABB’s DSQC620_C4/IRC5 ecosystem, separating it from other DSQC620_Cx capacitor units and related ABB components.
