The Allen-Bradley 700-HB33A1 U is a general-purpose plug‑in relay built on Allen-Bradley’s tall square blade-base platform, designed for compact control panels. It is powered by a 120 V AC coil (50/60 Hz) and provides three Form-C (3PDT) changeover contacts, enabling three independent switching circuits from a single device. This HB-series relay is rated for up to 15 A at 120 VAC and is suitable for signaling, interlock, and control logic tasks in industrial automation; variants in the HB family include options with pilot lights and other base configurations for different panel layouts.
