Product Description

The product identified as ABB HIER448845R1 is a Breaker Time Selection Module in the UNITROL hardware family.

Within the control architecture, this product serves the equipment role stated in its description and should be selected by exact model identity rather than by appearance or a broadly similar name. Service decisions should reflect the configured signal and control function.

UNITROL provides the platform context for this product, while the circuit breakers classification identifies its broader automation role. Exact application should follow the installed system configuration. This helps preserve the function assigned to the installed control node.

For maintenance or replacement work, the exact module designation should be checked against the installed hardware, wiring records, and control-system documentation before the component is placed into service. Maintenance planning should reference the installed hardware configuration.
