ABB 1SAM201906R1104 PS1-4-0-65 3-Phase Busbar 65A for 4x MS116/MS132 Manual Motor Starters

The ABB PS1-4-0-65 (SKU: 1SAM201906R1104) is a 3-phase busbar rated at 65A, designed to connect up to four MS116 or MS132 manual motor starters in a compact, parallel-feed arrangement. Part of ABB's PS1 busbar series, this component simplifies wiring in control panels by eliminating individual phase cables between motor starter groups, reducing assembly time and improving installation reliability. Its compact dimensions of 176.5 mm × 32.3 mm × 13 mm and lightweight construction at just 77 g make it well-suited for space-constrained enclosures.
