CATERPILLAR 155 KW GENERATOR
Overview
This Caterpillar SR-4 155 kW generator for sale in Mount Joy, Pennsylvania is an industrial three-phase standby generator showing approximately 2,330 hours and priced at $5,000. The Caterpillar data plate confirms a 155 kW / 194 kVA standby rating, 0.8 power factor, 60 Hz, 1,800 RPM, and a 3-phase, 10-wire configuration. Connection ratings are listed at 208 volts / 538 amps and 416 volts / 269 amps. The seller reports that the generator runs great once operating but has an intermittent issue with the electric starting system. For commercial, agricultural, industrial, shop, sawmill, or facility backup applications, this used Caterpillar generator offers substantial three-phase power capacity at a comparatively accessible asking price.
Available in Mount Joy, Pennsylvania, this Caterpillar SR-4 155 kW generator for sale is an open, skid-mounted industrial generator set showing approximately 2,330 hours and priced at $5,000.
The Caterpillar generator data plate provides considerably more information than was available in the original description. This unit is factory rated at 155 kW standby / 194 kVA, with a 0.8 power factor, 60 Hz frequency, 1,800 RPM operating speed, and 3-phase, 10-wire generator configuration.
The nameplate also shows reconnectable electrical ratings of 208 volts at 538 amps on the low-voltage connection and 416 volts at 269 amps on the high-voltage connection.
The seller reports that the generator runs great once operating. There is, however, one important known issue: the electric starting system works inconsistently and does not always start the unit as intended. The cause has not been diagnosed, so buyers should plan to inspect the starting circuit and determine what repair may be required.
155 kW Standby Caterpillar Generator
The generator-end plate identifies this unit as a Caterpillar SR-4 with a standby rating of:
155 kW
194 kVA
0.8 power factor
3-phase
10-wire configuration
60 Hz
1,800 RPM
That is important because the 155 kW figure shown on the plate is specifically a standby rating rather than a continuous-duty rating.
For buyers comparing used industrial generators, the data plate gives considerably more useful information than simply advertising the machine as a "155 kW CAT generator."
208/416-Volt Three-Phase Configuration
The generator data plate lists two connection ratings:
Low-voltage connection: 208 volts / 538 amps
High-voltage connection: 416 volts / 269 amps
The plate identifies the generator as a 3-phase, 10-wire unit.
This makes the generator potentially useful for commercial, agricultural, industrial, shop, manufacturing, sawmill, facility backup, and other applications requiring substantial three-phase electrical capacity.
A qualified electrician should verify the current lead configuration and confirm compatibility with the buyer's electrical system before installation or operation.
Caterpillar SR-4 Generator End
Additional information visible directly on the Caterpillar generator plate includes:
Generator Model: SR-4
Generator Frame: 445
Generator Part Number: 5N117
Generator Serial Number: 45BS857
Rated Speed: 1,800 RPM
Frequency: 60 Hz
Excitation: 27 volts / 10.3 amps
Power Factor: 0.8
The plate also includes the reconnecting diagram for both high- and low-voltage configurations.
These identification numbers give a buyer useful information for confirming parts, service information, and generator-end specifications.
Approximately 2,330 Hours
The photographed Caterpillar service meter shows approximately 2,330 hours.
For a commercial generator of this size, actual operating hours can be an important consideration when evaluating condition, previous use, and remaining service life.
Additional information regarding previous load conditions, whether the unit primarily served as standby power, and its maintenance history has not yet been supplied.
Original-Style Caterpillar Control Panel
The generator includes a substantial control and monitoring panel with analog instrumentation visible in the photographs.
Visible instrumentation includes gauges for items such as:
AC voltage
Frequency / Hertz
AC amperage
Engine oil pressure
Engine temperature
Power-related monitoring
Generator controls
Breaker controls
Warning and shutdown indicators
The panel also contains indicators for several operating or fault conditions.
The controls appear consistent with an older commercial Caterpillar generator installation rather than a simplified portable-generator setup.
Known Electric-Start Issue
The seller has been straightforward about one problem with the generator.
The electric starting system does not operate consistently every time.
The specific cause has not been determined.
Possible starting-system components should be properly diagnosed rather than assuming that the problem is simply a battery or starter. Depending on the cause, inspection could involve the starter circuit, batteries, wiring, switches, solenoid, engine controls, connections, or related components.
The seller reports that once the generator is running, it runs great.
Because this generator could potentially be used for standby or emergency applications, a buyer planning to depend on automatic starting should correct and test the starting issue before placing the generator into critical service.
Open Skid-Mounted Configuration
Photographs show the engine and generator mounted together on a heavy steel base.
The generator does not appear to have a sound-attenuated weather enclosure, making it more appropriate for an equipment room, generator building, covered installation, or another properly designed location unless the buyer adds suitable protection.
Buyers should also verify ventilation, exhaust, fuel supply, wiring, grounding, transfer equipment, and electrical-code requirements for their intended installation.
$5,000 Asking Price
At $5,000, this Caterpillar SR-4 offers a substantial amount of three-phase standby generating capacity for a buyer willing to investigate the intermittent starting concern.
The unit is located in Mount Joy, Pennsylvania.
