RS PRO 3 Site Transformer, 10 kVA, 400 V Primary, 110 V (55V-0V-55V) Secondary, Stand Alone, 32A Output, BS EN 122-6707

The RS PRO 122-6707 3 Site Transformer is engineered for robust voltage conversion in industrial and construction environments. Designed to step down a 400 V AC three-phase supply to a safe 110 V (55V-0V-55V) output, this transformer ensures reliable operation of power tools and site equipment. With a high power rating of 10 kVA and a 32A output current, it accommodates demanding loads and reduces electrical risks through centre-tapped earth connections.

Built into a heavy-duty portable steel case, the transformer is rated IP44, providing resistance against water spray and environmental factors commonly encountered on construction sites. This stand-alone transformer is equipped with BS EN 60309 industrial sockets, meeting European safety and functional standards, and facilitating easy connection to compatible devices.

Ease of portability is ensured with integrated strong handles, and the unit's dimensions -- 440 mm in length, 430 mm in width, and 500 mm in depth -- allow for efficient placement without occupying excessive space. Operating frequencies between 50 Hz and 60 Hz make it versatile across various regional supply standards.

Rigorously tested for reliability and compliance, the RS PRO transformer conforms to BS EN 61558 and BS EN 61558-20-23, making it an ideal solution for industrial, construction, and facility management applications that require both performance and enhanced safety. The centre-tapped secondary windings help to reduce shock risk and add an extra layer of protection for users.

10 kVA power rating suitable for heavy-duty and industrial applications. Primary voltage of 400 V and secondary voltage of 110 V (split phase 55V-0V-55V). Supplied with BS EN 60309 industrial rated sockets for secure connections.

IP44 rated steel housing withstands water spray and rough site conditions. Handles and stand-alone configuration ensure convenient transport and setup. Centre-tapped earth provides improved shock protection for safety compliance.
