1. Product Title

ABB 1TNA920611R0002‑ Control Circuit Printed Circuit Board

2. Product Overview

1TNA920611R0002 is an original ABB plug‑in control PCB designed for medium‑voltage switchgear and protection control assemblies. It implements signal conditioning, status feedback, interlock logic and backplane‑based internal data communication for switchgear control loops. On‑board filter circuits suppress field electromagnetic noise to guarantee stable signal transmission in heavy‑industry substations and power‑plant environments. This OEM spare part repairs signal dropout and logic‑related hardware faults, minimizing unplanned downtime of power distribution equipment.
