Product questions
What is ABB 1SAM201907R1101 used for?
It is the S1-M1-25, a flat, three-phase power infeed block for manual motor starter assemblies. It is a feeder terminal accessory, not a motor starter itself.
Which ABB motor starters are listed for the S1-M1-25?
The product information lists MS116 and MS132 manual motor starters. Confirm the exact starter, busbar configuration and equipment serial number before ordering; compatibility with other versions is not established here.
What current and voltage ratings does this infeed block have?
The rated operational current is 65 A and the rated operational voltage is 690 V AC or 250 V DC. The listed UL/CSA maximum operating voltage for the main circuit is 600 V AC.
Can the S1-M1-25 accept a 25 mm² cable?
The listed main-circuit capacity is up to 25 mm² for a rigid conductor, but up to 16 mm² for a flexible conductor. Conductor construction matters; confirm the connection requirements for the actual installation.
