Overview

The ABB Guard I™ Noise Isolation Transformer, SKU 9T10C1001G33, from ABB Electrification is engineered to provide critical noise reduction in industrial power systems. This unit effectively mitigates common mode noise, which occurs between neutral and ground conductors, and transverse mode noise. Common sources of this noise include electromagnetic interference (EMI), radio frequency interference (RFI), and ground loops, all of which can compromise the integrity of sensitive electronic equipment. Common mode noise, often stemming from variable frequency drives (VFDs), switching power supplies, and electrical discharge lighting, can lead to data corruption, sensor inaccuracies, and premature failure of control systems. The Guard I transformer isolates these noise signals, ensuring a cleaner power supply for Programmable Logic Controllers (PLCs), human-machine interfaces (HMIs), data acquisition systems, and communication networks where signal fidelity is paramount. Manufactured in the USA, the 9T10C1001G33 is designed for reliable operation in industrial settings. While specific kVA ratings are not detailed for this SKU, related ABB Guard I models are available in ranges such as 5-6 kVA and 8-10 kVA UL, indicating robust power handling capabilities for demanding applications. By filtering disruptive noise, this transformer helps to extend the operational lifespan of connected equipment and minimize costly unplanned downtime. It integrates into existing power protection strategies, offering a direct solution to power quality challenges in automation, manufacturing, and process control environments.
  • Provides common mode noise isolation between neutral and ground.
