Diesel Generator Sets with Cummins Engines, TC Series

Standby Power refers to the maximum output available for emergency use when utility power fails — it is intended for use with varying loads and is not suitable for continuous operation. Prime Power is the maximum power available for an unlimited number of hours per year in a variable load application. For most continuous or prime applications, the Prime Power rating should be used when selecting the appropriate genset model.

All models listed in the table — from TC30 to TC2000 — are available in both Open Type and Canopy Type configurations. The Open Type genset is suitable for installation in engine rooms or protected environments, while the Canopy Type provides weatherproof and noise-reduced enclosure for outdoor or noise-sensitive applications. Dimensional specifications for both configurations are provided in the table above.

The TC series generators use Cummins engines exclusively across the entire range. The engine series includes the 4B/4BT/4BTA (3.9L), 6BT/6BTA/6BTAA (5.9L), 6CTA/6CTAA (8.3L), 6LTAA (8.9L/9.5L), NTA/NTAA855 (14L), KTA19/KTAA19 (19L), KT38/KTA38 (38L), and KTA50 (50–50.3L) series — covering power outputs from 30 KVA up to 2000 KVA.

To select the correct genset, first calculate your total connected load in KW or KVA. For standby backup applications (e.g., emergency power during outages), use the Standby Power rating. For continuous or prime power applications (e.g., off-grid power supply or primary power source), use the Prime Power rating. It is generally recommended to size the generator so that your average load does not exceed 70–80% of the rated capacity to ensure longevity and fuel efficiency.

Yes. Each genset model in the table above has a dedicated PDF datasheet available for download via the "Details" button in the Download column. The datasheets contain comprehensive technical specifications including electrical performance, engine data, alternator details, dimensions, weight, and applicable standards. Simply click the corresponding "Details" button next to your desired model to access the PDF file.

The asterisk (*) and triangle (△) symbols indicate specific engine variants with different power output configurations. As noted at the bottom of the specification table: *4BTA3.9-G2 corresponds to QC 50/60E; △4BTA3.9-G2 corresponds to QC 58/67E; *6BT5.9-G2 corresponds to QC 86/100E; and △6BT5.9-G2 corresponds to QC 96/115E. These notations help differentiate engine tuning levels that result in varying KVA/KW outputs within the same engine platform.
