45 Amps, 3-Phase

Description

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%).

Standard Features

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.
