Product questions
What is ABB 1SAM201913R1103 used for?
ABB 1SAM201913R1103, also designated S1-M3-35, is a three-phase power infeed block for connecting feeder conductors to a motor-starter busbar system. It is an accessory, not a motor starter.
Sources
Which conductor sizes can the S1-M3-35 accept?
The main circuit accepts one flexible or rigid conductor from 10 to 35 mm². The listed UL/CSA range for flexible and stranded conductors is 8–2 AWG. Verify conductor type and installation requirements for the intended circuit.
Can the S1-M3-35 be used with an MS132 Type E application?
The S1-M3-35 can provide line-side terminal spacing for MS132 Type E or Type F applications. Confirm the complete starter configuration and applicable ratings before selecting it; the infeed block alone does not establish the assembly rating.
Sources
What are the current and voltage ratings of the S1-M3-35?
The block has a rated operational current of 100 A and a rated operational voltage of 690 V AC or 250 V DC. Its listed UL/CSA maximum operating voltage is 600 V AC. Check the complete circuit and applicable standard when selecting ratings.
