ABB PS1-5-2-65 Industrial Safety Relay Module

ABB PS1-5-2-65 is a 3-phase busbar designed for ABB's PS1 mounting system, enabling five MS116, MS132, or MO132 motor starters to be mounted on a single PS1 current rail. It is rated for 690 V AC and 65 A, with a 17.5 mm pitch that matches standard PS1 spacing for easy integration with other PS1 modules. The assembly includes two lateral auxiliary contacts to facilitate simple connection of basic control circuits alongside the power conductors. As a dedicated PS1 accessory, the PS1-5-2-65 provides a compact, shared connection point for distributing three-phase power to five starters in one module, reducing wiring complexity within control enclosures and simplifying panel layouts for multi-start configurations. When used with MS116, MS132, or MO132 starters, this busbar supports a five-station starter setup on a single rail, offering a robust solution for industrial motor control applications that rely on ABB's PS1 hardware ecosystem.
