Cat rounds out its 20- to 400-kW line of mobile, diesel generator sets with the XQ175, rated at 175 kW. The new genset is driven by the Tier-3-certfied Cat C6.6 engine, with ACERT technology. A radiator-compartment door allows easy access for radiator cleaning. The generator is capable of switching between 480/277-V or 208/120-V, 3-phase operation through a voltage changeover board that has fewer moving parts than the traditional voltage-selector switch. Cat says the permanent-magnet generators improve motor starting and load control. Camlock distribution connections, sheet steel enclosures (pretreated with zinc phosphate before polyester powder coating), and dual wall UL-approved fuel tanks are standard equipment.
