PULLEY 4P2843 - Caterpillar

The SR4 Brushless Generator is suitable for application to all kinds of loads, including, but not limited to: mixed loads of motors and lights, SCR-controlled equipment, computer centers, communication installations, and petroleum drilling applications. The elimination of brushes in the field circuit reduces maintenance, improves reliability and provides a higher degree of protection in potentially hazardous atmospheres.The generator set packages can be utilized for prime or stand-by power generation, in land based or marine applications.SR4 generators are utilized in single phase, half wave excitation and regulation, and three phase, full wave excitation and regulation. The generators are either four pole or six pole design with four, six, ten or twelve lead configuration depending on frame size. They are capable of producing electrical power in either 50 Hz or 60 Hz applications.Generator Identification
The generator identification and information plate is located on the left side of the generator.When service is required, use the information given on these plates. The information contains the serial number, model number and the generator set (engine and generator) rating. All pertinent generator data is also included on the plate to provide the necessary information to order parts. and Output Lead Wiring
All generator lead wiring information can be found on the information plate, or on a decal on the power lead side of the generator for twelve lead generator sets. If the generator is equipped with a circuit breaker, the decal will be mounted on the sheet metal of the circuit breaker panel.
