Our Repair Process for the
70 AS 30a-E
Our repair process for ABB 70 AS 30a-E auxiliary contact blocks begins with a thorough inspection of contact surfaces for signs of wear, pitting, or contamination. We then verify spring tension to ensure it meets specified tolerances, guaranteeing proper contact pressure and reliable switching. Terminal connections are meticulously examined for corrosion, and terminal screws are tightened to the correct torque to eliminate any loose connections. If contact surfaces are damaged, spring tension is outside of tolerance, or terminal corrosion is present, the auxiliary contact block is replaced to ensure proper circuit operation and prevent system downtime.
