Allen-Bradley 700-HA33A1 General Purpose Tube Base Relay

Allen-Bradley 700-HA33A1 General Purpose Tube Base Relay is a three-pole, three-throw plug-in relay designed for use with Allen-Bradley 700-H tube-base sockets. It employs a 120 V AC coil and delivers three independently switched contacts, each rated to 10 A, enabling a single coil to drive up to three separate circuits. This general-purpose relay is built for reliability in industrial control panels, with a tube-base mounting style that supports quick installation and field replacement in legacy systems without rewiring wiring harnesses. The unit supports operation at standard line frequencies (50/60 Hz), making it compatible with a broad range of power environments. As part of the 700-HA family, the 700-HA33A1 provides a robust, widely used solution for common automation tasks such as sequencing, interlocking, and signaling within machines, conveyors, and processing equipment. Its straightforward, durable construction and common 120 V AC coil variant help ensure consistent performance across demanding industrial settings, while maintaining compatibility with a wide ecosystem of Allen-Bradley accessories and base sockets for maintenance and serviceability.
