Description

Brief Product Description

The Allen-Bradley 80172-110-02-3 is a high-reliability thyristor unit utilizing Gate Commutated Turn-off (GCT) technology to provide precision motor control and safety interfacing. Optimized for the SMC-3 soft starter series, it delivers a 17 Amp capacity with integrated diagnostics for demanding industrial safety applications.

Product Description

High-Performance Power Commutation

The Allen-Bradley 80172-110-02-3 represents a specialized class of thyristor units designed to manage high-stress electrical loads within industrial motor control centers. By leveraging advanced Gate Commutated Turn-off (GCT) semiconductor technology, this module ensures efficient power switching and commutation. It primarily functions within the SMC-3 soft starter ecosystem, where it regulates current flow to provide smooth acceleration and deceleration for three-phase motors. This controlled approach reduces mechanical wear on drive components and prevents electrical inrush spikes that can destabilize local power grids.

Advanced Safety and Diagnostic Integration

This thyristor unit incorporates a dual-channel architecture and force-guided contacts to meet the most stringent international safety benchmarks, including SIL 3 and PLe ratings. Because machine protection is paramount, the 80172-110-02-3 features a comprehensive suite of diagnostic tools. Integrated LED indicators provide immediate visual feedback regarding the operational status and fault conditions of the unit.¹ Furthermore, the inclusion of a manual reset function allows maintenance personnel to safely restore operations only after verifying that all safety parameters have been satisfied. These fail-safe mechanisms ensure that the system remains protected against overcurrent events and electrical anomalies.

Robust Industrial Design

Engineered for the rigors of heavy industry, the Rockwell Automation 80172-110-02-3 maintains stable performance despite significant temperature fluctuations and vibration. Its compact form factor allows for high-density installation within control cabinets, maximizing the use of panel space. The unit operates reliably on a standard 110-120V AC control voltage, making it compatible with a wide variety of existing automation infrastructures.² Additionally, the force-guided contact design prevents the welding of contacts during fault conditions, ensuring that safety circuits can always open when required by the controller.
