Overview
The Allen-Bradley 595-A auxiliary contact block is a modular contactor accessory that adds discrete control contacts to Allen-Bradley 500-line and Bulletin 509 motor starters. This 1NO (Normally Open) contact block operates at 600VAC, 10 Amps and is suitable for NEMA sizes 0–5 applications. Commonly used for status indication, pilot device interlocking, and auxiliary control logic, the 595-A integrates seamlessly into existing control panels and motor control systems.
