Caterpillar 3306 Generator Set Data Plate – 230 kW Standby, 240V 694A, Year 2000

This photograph shows the data/specification plate on a Caterpillar generator set, apparently powered by a Caterpillar engine (model appears to be 3306, though the header line is blurry). The plate rates the unit at approximately 262 kVA / 230 kW at 60 Hz, with the 'STANDBY' duty box marked with an X (Prime and Continuous unchecked). The Generator Data section states it is a 3-phase, 12-wire machine, connected WYE (X marked) in parallel configuration, producing 240 volts at 694 amps. Excitation is listed as 38 volts at 7.1 amps. The generator uses a 446 frame and runs at 1800 rev/min. Maximum temperature rise is 130 °C by resistance, based on 40 °C ambient and 1000 meters altitude, with Class H insulation. The enclosure type field is blank, and the year of manufacture is stamped as 2000. A footnote instructs the reader to include the serial number and generator part number from the generator serial number plate when ordering or referencing the unit. Note: although uploaded to a 1991 Ford LTD Crown Victoria gallery, this plate is for industrial generator equipment, not the Ford vehicle.
