Overview#
The Triton Power TP-JD350-T3-UL is a 350 kW (438 kVA) diesel standby generator powered by the John Deere 6135HFG09 turbocharged six-cylinder engine with 13.5 L displacement. As a Tier 3 unit, it avoids the aftertreatment complexity of Tier 4 Final models while still meeting EPA requirements for stationary emergency standby applications. The UL2200 listing confirms compliance with safety standards required by most building codes for commercial generator installations.
Paired with a Leroy Somer alternator, the TP-JD350-T3-UL delivers reliable three-phase power at 1800 RPM in 120/208V and 277/480V configurations. The 6135 platform's 13.5 L displacement provides ample power reserve for motor starting and block loading typical of large commercial facilities.
Our service experience#
The John Deere 6135 is the workhorse of the 300-400 kW generator class, and its Tier 3 configuration eliminates the DPF and SCR maintenance that adds cost and complexity to Tier 4 Final units. For qualifying stationary emergency standby installations, this translates to meaningfully lower total cost of ownership. The UL2200 listing streamlines AHJ (Authority Having Jurisdiction) approval for commercial projects, which is a significant advantage during the permitting process.
