Overview

The ABB Guard I™ Noise Isolation Transformer (SKU: 9T10A1008G33) is a 300 kVA, three-phase, dry-type transformer designed to protect sensitive electronic equipment from electrical noise. Manufactured by ABB Electrification in the USA, this transformer mitigates common mode noise between neutral and ground conductors, as well as transverse mode noise between primary and secondary coils. Common mode noise, caused by electromagnetic interference (EMI), radio frequency interference (RFI), and ground loops, is reduced by up to 120 dB thanks to a grounded full-width copper electrostatic shield integrated between windings. Transverse mode noise is attenuated by up to 30 dB. The transformer features a 480V Delta input and a 208Y/120V output, with voltage taps offering +2, -2: 2.5% tolerance for precise output voltage adjustment. Constructed with copper coils for optimal conductivity and efficiency, this model is ideal for critical industrial systems requiring reliable noise isolation. Optional accessories include rain shields for NEMA 3R enclosure conversion and stainless steel (316) enclosures for outdoor applications up to 150 kVA. With a UNSPSC code of 39121029 and a US country of origin, the ABB Guard I™ ensures enhanced reliability and reduced downtime in sensitive environments.
