Generac XG04045CNAX 40kW Protector XG 208/240/480 V 3-Phase Standby Generator

The Generac 40 kW Generator adds well-known features to new improvements with the Protector XG series. The 40kW XG04045 has a 4.5 Liter engine that runs at 1800 RPM under load and 1200 RPM during self test or at low idle. A NEW  Power Zone® 410 Controller brings the latest in technology with additional functionality and more features than ever before, including the ability to select the fuel type at the controller without any other modifications. This controller is NFPA 110 capable.

Voltage Control Cartridges

XG 3-Phase generators have a 12-lead alternator hardwired to a terminal block. A Voltage Control Cartridge (VCC) makes the necessary connections for 208 Volt, 240 Volt, or 480 Volt 3 Phase current. Generac Configures the 3-Phase Generators at the factory with a 208-Volt VCC . At Installation, the installer can replace the 208 VCC with a 240 or 480-Volt VCC.

• 120/240 Volts 3 Phase ("J" Voltage) - (VCC Included)
• 277/480 Volts 3 Phase ("K" Voltage) - (VCC Included)
• 120/208 Volts 3 Phase ("G" Voltage) - (VCC Installed)

Circuit Breaker Kits

The Power Zone 410 Controller provides over current protection on XG Series 3-Phase Generators. Optional Circuit Breaker kits are available if required by the Authority Having Jurisdiction or the installation needs a disconnecting means.

Typical 80kW Circuit Breakers

• 120/208 Volts 300 Amp 3-Pole Circuit Breaker G0099810
• 120/240 Volts 300 Amp 3-Pole Circuit Breaker G0099810
• 277/480 Volts 150 Amp 3-Pole Circuit Breaker G0099080

Use with RTS 3-Phase Transfer Switch

Important: Installation with an RTS 3-Phase Transfer Kit Requires a 3-Phase Voltage Sensing Kit

• 120/208 Volts 3 Phase ("G" Voltage)
• 120/240 Volts 3 Phase ("J" Voltage)
• 277/480 Volts 3 Phase ("K" Voltage)

40kW Standard Features

The new XG series carries forward the familiar features found in earlier models like quiet operation. A Generac 4.5-liter engine beats the competition on fuel efficiency for comparable generator models that produce less power. The 40kW XG maintains its UL-2200 listing along with the EPA Certification. An aluminum enclosure guards the generator against corrosion. Protected by a Generac 5-year/2000-hour limited warranty.

Generac didn’t stop with the features that Protector Series users came to expect.

New 40 kW Generator Features

New Electro-Galvanized base frame components prevent rust and corrosion. Single-side regular maintenance make service fast and easy through the front, key-locked panel. Change or check the oil, oil filter, and air filter; check or change the coolant; replace the spark plugs and check the battery. 

Fuel setup is made easier than ever through the controller. Set the 40 kW generator fuel type in the controller—no other adjustments are necessary. 

The generator exercises at 1200 RPM for a peaceful 58 dBA noise level and 64 dBA under normal load. The PowerZone 410 Controller has more features and more capability than ever before, including an overload control that eliminates the need for a circuit breaker.

Cellular connectivity is standard for Mobile Link & Fleet.
