Product questions
What is ABB 1SAM201907R1103 and which motor starters is it intended for?
ABB 1SAM201907R1103 is the S1-M3-25, a three-phase power infeed block for MS116 and MS132 manual motor starters. Confirm the starter model and installation requirements before ordering.
What conductor sizes can the S1-M3-25 accept?
The main-circuit terminals accept one rigid conductor of 2.5–25 mm² or one flexible conductor of 2.5–16 mm². For flexible conductors with ferrules, the listed range is also 2.5–16 mm².
What are the current and voltage ratings of the S1-M3-25?
The block is rated at 65 A operational current and 690 V AC or 250 V DC operational voltage. The listed UL/CSA maximum operating voltage for the main circuit is 600 V AC. The complete installation may have lower limits.
Can the S1-M3-25 be used for Type E or Type F applications?
The block provides line-side terminal spacing for MS132 applications described as Type E or Type F. This alone does not establish the rating of a complete assembly; verify the specific starter and configuration against ABB documentation.
