The ABB 9T10C1002G03 Guard I 30Kva Noise Isolation Transformer is designed to provide superior noise attenuation, effectively reducing common mode noise caused by electromagnetic interference, radio interference, and ground loops. This is achieved through a copper shielding between the primary and secondary coil windings, which minimizes capacitive noise coupling that can disrupt electrical systems. The transformer is UL Listed and UL Energy Verified, ensuring high standards of safety and efficiency. It is available with either aluminum or copper windings and comes in all three temperature rise ratings, including low audible noise options. Additionally, it meets the seismic qualifications of IEEE-693-2005, IBC-2021, and CBC 2022, making it a reliable choice for environments requiring robust seismic performance.
