    About the Manufacturer

    In 1969 Reliance introduced the compact and rugged Series 500 time switches. The Series 500 has been used on billboards, water heaters, lighting and any place electrical power needs to be controlled on a daily schedule. Today the Series 500 is the quality standard for the industry.

    In 1983, Reliance introduced the first manual transfer switches engineered specifically for use with portable generators of up to 5000W.

    In 1995, Reliance Controls Corporation introduced Panel/Link® manual transfer panels and generator-ready load centers for use with standby generating systems to 31.5kW.

    In 1999, Reliance Controls Corporation introduced the Easy/Tran® for use with traffic signals, cell towers, irrigation systems, community well pumps and more. The Easy/Tran is the original “point-of-use” transfer switch.

    In 2003, the original Reliance Gen/Tran(TM) line of manual transfer switches was replaced with the vastly improved Pro/Tran® Series which accommodates portable generators of up to 12,500W. The Pro/Tran® is also the first loadside transfer switch to be listed to the new, and more stringent, UL1008 standard.

    In 2005, Reliance Controls Corporation added the Pro/Tran® Q Series. The Q is a totally unique loadside transfer switch featuring conventional 1-inch interchangeable circuit breakers for easy upgrading and adjusting of branch circuit protection on the generator side of the transfer switch. It is ideal for heavier residential loads such as water heaters, deep well pumps, septic lift stations and central air conditioners. The Q Series is available with the exclusive Reliance electronic bar graph meter which monitors voltage and wattage on each generator leg.

    As the leader in portable standby power integration, Reliance Controls Corporation has contributed more innovations than any other single manufacturer and has been awarded over 30 patents on manual transfer switches and accessories. And after nearly a century of innovation, Reliance Controls Corporation has built an enviable reputation for high quality, superior engineering and exceptional customer service.

      Good transfer switch

      from Los Alamos, NM

      This transfer switch serves as the main disconnect for our house. It is outside and feeds a 200 Amp breaker panel inside. I can manually disconnect my house from the county's utilities and connect it to my generator. My electrician said it was well constructed and was pleased to install it.
