D45AT6 — Three-phase autotransformer 230 → 400
Three-phase autotransformer intended for homes and residential installations with a 230 V three-phase supply that need to power equipment or a circuit designed for 400 V. It adapts voltage without providing galvanic isolation.
The IP65 version provides a higher level of protection against dust and water, making it more suitable where the residential installation requires a more protected enclosure. Final location must comply with the intended installation and service conditions. As an autotransformer, input and output are not electrically isolated; suitability for the equipment and the home's protection scheme must be checked. It is also designed for residential use with quiet operation and low energisation inrush current, reducing the risk of nuisance circuit-breaker tripping.
