The Allen Bradley 1406-G is a sophisticated programmer unit intended for robust protection and monitoring applications. This unit stands out with its modularity, supporting a protective module as well as a programmer/monitoring module. It can also accommodate an optional RTD module, which increases its functionality in various configurations.

This device is designed to handle input current transformer ratings that span from 25 A to 1500 A, catering to a wide range of requirements. The full-load current specifications extend between 15 A and 800 A, providing ample capacity for diverse operational needs. Featuring an RTDs winding type, it ensures reliable thermal performance during use.

The 1406-G includes programmable features, such as phase unbalance protection to mitigate risks associated with uneven loads, along with undervoltage protection that can be set to specific percentages of line voltage. Additionally, users can program the trip delay for both protections, enhancing operational safety. Ground-fault protection is integrated with a primary rating of 1 A to 25 A, ensuring safety in the presence of earth faults.

For scenarios involving potential jams, the unit incorporates jam protection that can trip at 2 to 10 times the full-load current, effectively preventing motor damage. The terminals for connecting wiring utilize screw terminals, ensuring solid connections.

The enclosure is constructed from materials typical for switchgear, providing durability and effective safeguarding for the internal components of the programmer unit. Overall, the Allen Bradley 1406-G is versatile, robust, and well-suited for comprehensive monitoring and control in industrial applications.
