Overview
The Allen-Bradley 700-HD33A1 is a general-purpose, industrial-grade relay designed for panel-mount and flange-cover applications. With 3 poles, double-throw (3PDT) contact configuration and a rated contact current of 15 A at 120 V AC (50/60 Hz), this relay delivers reliable switching for automation, motor control, and industrial electrical circuits. The square base design with blade-style terminals ensures secure connections in standard panel layouts.
