Overview

ABB Guard I™ Noise Isolation Transformer (SKU: 9T10A1005G33) is a dry-type, low-voltage transformer designed to suppress electromagnetic interference (EMI), radio frequency interference (RFI), and ground loop noise in industrial power distribution systems. This 150 kVA, 480V Delta to 208Y/120V transformer features a grounded full-width copper electrostatic shield between primary and secondary windings, delivering up to 120 dB of common mode noise attenuation and up to 30 dB of transverse mode noise attenuation. Common mode noise—caused by EMI, RFI, or ground loops—can disrupt sensitive electronics, corrupt data, and reduce equipment lifespan. The Guard I™ transformer isolates neutral and ground conductors, blocking disruptive signals before they reach critical loads like PLCs, sensors, or variable frequency drives. With NEMA 2 construction and optional rain shields for NEMA 3R enclosures, this transformer is built for harsh industrial environments. Available in aluminum or copper coil configurations with 115°C or 150°C rise ratings, it supports three-phase systems up to 300 kVA. Key applications include manufacturing plants, data centers, healthcare facilities, and renewable energy systems where power quality is paramount. The transformer’s electrostatic shield and high attenuation ratings ensure stable power delivery, protecting downstream equipment from voltage spikes, harmonics, and transient noise. Manufactured in the USA by ABB Electrification, the 9T10A1005G33 meets DOE 2016 energy efficiency standards and is distributed by Gross Automation. Choose Guard I™ to extend the lifespan of sensitive electronics, prevent data corruption, and maintain consistent power quality in your facility.
