Overview

ABB’s Guard I™ Noise Isolation Transformer (SKU: 9T10C1002G03) from ABB Electrification is a UL-listed isolation transformer designed to suppress electrical noise in sensitive industrial and medical environments. This transformer isolates common mode noise between neutral and ground conductors, as well as transverse mode noise, ensuring stable power delivery to critical equipment. Common mode noise sources—such as electromagnetic interference (EMI), radio frequency interference (RFI), and ground loops—are effectively neutralized, while transverse mode noise is attenuated to maintain clean power quality. Constructed in the U.S. to meet UL standards, the Guard I transformer is rated for 8-10 kVA and is suitable for automation and control systems, including PLCs and VFDs, as well as medical diagnostic and therapeutic devices. Data centers relying on stable power for servers and networking hardware, and manufacturing environments with precision machinery, benefit from reduced electrical interference. By minimizing noise-related disruptions, this transformer extends equipment lifespan, reduces unplanned downtime, and enhances operational reliability. The transformer is part of ABB’s ISO TX RT G2 series, designed for high-reliability applications where power quality is non-negotiable. Its robust construction and compliance with UL standards ensure consistent performance in demanding industrial settings. For facilities where electrical noise poses a risk to sensitive electronics, the Guard I transformer provides a proven solution to safeguard operations.
