Diesel Generator Sets with Cummins Engines, TC Series

Standby Power (ESP) refers to the maximum output available for use in the event of a utility failure. It is typically used for limited hours per year with varying load. Prime Power (PRP) is the maximum power available for an unlimited number of hours per year with a variable load. For most continuous or critical applications, Prime Power ratings should be used as the reference.

These symbols indicate specific engine variants with corresponding alternator configurations. For example: *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. Please refer to the footnote at the bottom of the specification table for the complete reference.

Open Type generator sets have no enclosure and are generally installed indoors or in a purpose-built generator room. They are more compact and lower in cost. Canopy Type generator sets are enclosed in a weatherproof housing, making them suitable for outdoor installation. The canopy provides protection against rain, dust, and noise reduction. As shown in the table, canopy units are larger in overall dimensions than their open-type counterparts.

For large industrial facilities, hospitals, or data centers requiring high and continuous power output, models such as TC1375 (KTA50-G3, 1345 kVA Standby), TC1650 (KTA50-G8 / KTA50-GS8, 1650 kVA Standby), TC1875 (KTA50-G15, 1873 kVA Standby), and TC2000 (KTA50-G16, 2000 kVA Standby) are ideal. These units feature large-displacement Cummins KTA50 engines and deliver prime power up to 1500 kW.

Fuel consumption (L/h) is a key factor in calculating operating costs. Smaller models such as the TC30 consume as little as 6.7 L/h, while larger models like the TC2000 consume up to 404.8 L/h at full load. When selecting a generator, consider your average load factor — generators typically operate most efficiently at 70–80% of rated load. Choosing an appropriately sized unit avoids fuel waste from under-loading or overload risk from over-loading.

Yes. The dimensions listed in the table represent standard configurations for Open Type and Canopy Type units. Custom configurations — including special enclosures, soundproofing levels, fuel tank capacities, control panel options, and parallel operation setups — can be arranged based on specific project requirements.
