ABB PS1-4-0-65 is a 3-phase PS1 busbar module rated for 65 A per phase, designed to mount four motor circuit breakers (MS116, MS132, MO132) within ABB's PS1 distribution system. This accessory provides a compact, modular busbar configuration with 4-MMP connections and 0-AUX, suitable for integration into industrial automation panels. In industrial settings, it serves as the central three-phase feeder that groups four motor-starting circuits on a single bus, simplifying layout and enabling clean separation of phases for reliable motor protection.
