Performs with High Efficiency up to 97.8% Not only is the S3MT-100KWR480V wrap-around transformer very efficient, with up to 97.8 percent efficiency, but it is also very quiet with a noise profile less than 65 dBA. Built-in circuit breakers on both transformers help prevent dangerous power overloads. Eight ball-bearing cooling fans help prevent overheating. An overheat-sensing relay and switch combine with red alarm indicators to provide over-temperature warning and overheating protection. Small Footprint for Quick Installation in a Compact Space The compact footprint enables installation of the S3MT-100KWR480V with minimal space.
