Outdoor Manual Transfer Switch
50 Amps, 10 circuits, 125/250V

PRO/TRAN® 2 by Reliance Controls

Reliance Controls Corporation is pleased to announce our next generation of manual transfer switches. The new PRO/TRAN®2 line of Loadside™ switches features all of the benefits which made the original Pro/Tran® an industry leading product for over 30 years, while incorporating a number of new features to give our customers exactly what they are looking for.

®2 utilizes conventional 1-inch interchangeable circuit breakers. All models are UL Listed for all popular brands and types of breakers, including AFCI and GFCI. They can be easily re-configured in the field for multiple double pole circuits if needed. All models also include a hinged non-metallic protective cover which also provides a finished appearance. Optional new color-coded watt meters are included on many models, and assist in balancing the generator load. Like all Reliance Pro/Tran® transfer switches, the PRO/TRAN®2 is completely prewired for fast installation.

®2 Series is UL Listed to UL Standard 1008 and is suitable for use in accordance with article 702 of the National Electrical Code ANSI/NFPA 70.
