Product Information

Generac Automatic Transfer Switch for Generator

Please select your option at checkout. Either 45Amps 3-Phase or 70Amps Single-Phase.

Generac Transfer Switches are designed for use with single-phase and 3-phase 50Hz generators. The transfer switches are certified for IEC 60947-6-1 – the transfer switch standard – where electronically operated and mechanically interlocked contacts are required for safety. For the 3-phase switch, the load transfers to the generator when any phase fails, when phase sequence is incorrect, or when there is over or under voltage (±10%).

Generac Transfer Switches are available with steel enclosures for 45 and 70 amp single phase and 3-phase models. The enclosure is RAL 7035 painted, and certified to IEC IP66. The contactors equipped comply with a wide range of certificates and marking, including the CE mark. The controller at the generator senses and controls the timing, exercising, and transfer commands.

Blue Diamond can provide a total solution for your power backup requirements supplying the ATS, Generator and the Electrician to come out and install and program your setup, taking all the hassle out of it!
