ABB S1-M1-25 1SAM201907R1101 1P Busbar 25A power infeed

The ABB S1-M1-25 (article 1SAM201907R1101) is a three-phase power infeed block designed for direct use with MS116 and MS132 manual motor starters. It accepts supply cable cross sections up to 25 mm², making it the right choice where larger conductors must be connected to the starter assembly. The flat mounting form keeps the overall assembly compact, and the block carries a rated current of 65 A.

Technical specifications:

• Series: S1-M1-25
• ABB article number: 1SAM201907R1101
• EAN: 4013614400803
• Type: 3-phase power infeed block
• Compatible motor starters: MS116, MS132
• Maximum cable cross section: 25 mm²
• Rated current: 65 A
• Mounting form: Flat

Features and benefits:

• Accepts cable cross sections up to 25 mm², enabling connection of larger supply conductors without external terminal adapters
• Direct compatibility with MS116 and MS132 manual motor starters simplifies panel assembly and reduces component count
• Flat mounting form supports compact switchgear and control panel layouts
• Single three-phase infeed block handles all three supply phases, keeping the supply-side wiring tidy
