This Protector gaseous generator supports natural gas or vapor propane fuel and is part of the Generac Liquid Cooled XG Series. The supplied product data lists this model as a no-catalyst configuration and notes that it is not available for purchase in California or Massachusetts. For 120\/208V 3-phase applications, the unit includes the appropriate Voltage Configuration Cartridge based on the supplied product note. For 120\/240V 3-phase or 277\/480V 3-phase applications, the appropriate Voltage Configuration Cartridge and circuit breaker must be ordered for the system to function correctly.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003e40kW Standby Power for 3-Phase Applications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe XG04045CNAX is intended for standby generator projects where 40kW output, 3-phase service, and voltage configuration planning are required.
