This 350kVA 60Hz Cummins generator is widely used in:
Its combination of power, efficiency, and durability makes it suitable for both continuous and emergency operation.
Q1: Is the 350kVA Cummins generator suitable for continuous operation in industrial environments?
A1: Yes. The 6LTAA9.5-G1 Cummins engine is designed for heavy-duty applications and offers excellent load acceptance and stable performance. It is well-suited for factories, commercial buildings, and large facilities requiring reliable prime or standby power.
Q2: What voltages are available for the 60Hz configuration?
A2: Hosem Power can configure the generator for multiple 60Hz voltage options, including 120/240V, 127/220V, 220/380V, 240/416V, and 277/480V, depending on your project or regional requirements.
Q3: Does this generator support automatic power switching?
A3: Yes. The generator is fully compatible with ATS (Automatic Transfer Switch) systems, enabling automatic start-up and load transfer during grid outages for seamless backup power.
Q4: What is the noise level of the soundproof version?
A4: The soundproof canopy uses industrial-grade acoustic insulation, optimized airflow channels, and a low-noise muffler. This keeps operating noise at levels suitable for commercial and residential proximity, depending on installation conditions.
Q5: How often does the generator require maintenance?
A5: Basic maintenance—such as oil, filters, and coolant checks—is recommended every 250–300 hours, depending on operating conditions. The soundproof canopy’s wide-access doors make servicing fast and convenient.
