Busbar infeed for MS325 motor starter bases
The ABB MS325-BB1 is a busbar power infeed block that connects line-side power to the MS325 motor starter base. It terminates as a high-connection terminal block on the S3-M2 busbar system. This accessory lives in the ABB MS325 family, which covers manual motor starters and their busbar distribution. The BB1 variant is the infeed block — the part that brings the supply phase onto the busbar rail.
