Overview
The Allen-Bradley 595-A Series B is a single-pole auxiliary contact block engineered for reliable secondary switching in motor control and industrial automation applications. Rated at 600V and 10A with a 1NO (normally open) contact configuration, this side-mount block integrates seamlessly with NEMA size 0-5 contactors and starters. The 595-A provides supplementary switching logic without modifying the primary control circuit, making it ideal for status indication, interlock chains, and pilot device triggering.
