• Potencia nominal: 30 kW

• Voltage: 120/208 Volts

• Rated Amps: 104.1 Amps

• Frecuencia: 60 Hz

• Voltage Regulation: ±1.0%

This generator is capable of supporting:

• 5-ton HVAC systems

• Elevators in low-rise buildings

• Small data centers

• refrigeración comercial

• Workshop machinery

The alternator is a brushless 4-pole, 12-lead revolving field design, which enhances reliability and reduces maintenance requirements.

Quiet Connect Series Design and Noise Control

The Quiet Connect series is engineered for minimal acoustic impact. The RS30 operates at just 65 dBA, which is remarkably quiet for a commercial standby generator of this size.

The aluminum Sound Level 1 enclosure provides:

• Resistencia a la corrosión

• Wind load rating up to 180 MPH (ASCE 7-10 compliant)

• Puertas de servicio desmontables

• Professional appearance for visible installations

If ultra-quiet performance is required, optional Sound Level 2 kits are available.

For property managers, healthcare facilities, and residential estates where noise compliance matters, this feature is critical.

Sistema de control digital PowerCommand 1.1

The RS30 includes the advanced Sistema de control PowerCommand 1.1, which integrates complete generator management in one platform.

Core features:

• Pantalla LED retroiluminada de 128 x 64 píxeles.

• Capacidad de arranque/parada remota

• Self-diagnostics

• Alarm and shutdown notifications

• Regulación precisa de voltaje y frecuencia

• NFPA 110 Level 1 compliance (with required accessories)

Unlike entry-level controllers, PowerCommand provides industry-leading diagnostic insight. Service technicians can identify issues quickly, minimizing downtime.

This system also supports flexible exercise scheduling. The generator can be programmed to run as little as 2 minutes every 6 months, reducing unnecessary fuel consumption while maintaining readiness.

Cold Weather Performance Down to -40°F

El Generador Cummins de 30 kW, serie Quiet Connect RS30, 120/208 voltios, trifásico. is engineered for extreme climates.

Factory-installed features include:

• Calentador de refrigerante

• Calentador de ventilación del cárter

• Gran soporte para baterías

• Línea de combustible flexible

With these systems in place, the generator can start in temperatures as low as -40°F.

For facilities in northern climates, this is a major advantage over standard air-cooled units that struggle in freezing conditions.

---

Fuel Efficiency and Operating Costs

Consumo de combustible a plena carga:

• Natural Gas: 380.9 cubic feet per hour

• Propane: 4.5 gallons per hour

At half load:

• Natural Gas: 219.0 cubic feet per hour

• Propane: 2.7 gallons per hour

Because this is an 1800 RPM liquid-cooled unit, it delivers efficient long-duration operation. For standby applications requiring extended runtime, this platform is far more suitable than high-speed portable alternatives.

---

Installation Considerations and Transfer Switch Pairing

The RS30 requires a prepared mounting pad and proper ventilation clearances. It uses a 125-amp mainline breaker and requires a 12V battery rated at 550 CCA at 0°F.

Recommended transfer switch: Cummins OTEC ATS.

For three-phase commercial installations, professional sizing and load analysis are essential. This ensures compliance with NEC and local electrical codes.

If your project demands higher output, consider comparing this model with:

• Generador Cummins RS125 Quiet Connect de 125 kW, 120/240 voltios, trifásico.

• Generador Cummins RS125 Quiet Connect de 125 kW, 277/480 voltios, trifásico.

For smaller facilities, you may evaluate:

• Generador Cummins Quiet Connect Series RS25 de 25 kW, 120/240 voltios, trifásico.
  The RS30 fills the gap between light commercial 25kW units and heavy-duty 125kW systems.

Practical Steps Before Purchasing

1. Conduct a professional load calculation.

2. Confirm three-phase 120/208V requirement.

3. Decide between natural gas or propane supply.

4. Verify pad dimensions (94L x 34W x 45.5H inches footprint).

5. Ensure proper clearance and airflow.

6. Pair with an appropriately rated automatic transfer switch.

Expert recommendation: Always plan for 20–25% headroom above your calculated load to prevent continuous full-load operation.
