Kohler Power RDT Series 240V 200A Automatic Transfer Switch
Product Description
The Kohler Power RDT Series 240V 200A Automatic Transfer Switch (ATS) is designed to automatically manage the transition between utility power and a compatible standby generator. It continuously monitors the utility source and, when an outage occurs, coordinates with the generator to transfer electrical loads to backup power. When utility power is restored, the switch automatically transfers the load back to the utility source.
The standard 200A RDT configuration is the RDT-CFNC-0200A-QS7, a single-phase, 2-pole, 240V transfer switch without a load center. It uses Kohler's MPAC 500 microprocessor-based controller and is designed for single-phase KOHLER residential and small-business generator systems.

- Suitable for indoor or outdoor installation
- Optional audible alarm accessory board
- Optional external alarm module
- 5-year limited warranty
Automatic Power Transfer
The RDT serves as the control point between the utility supply, standby generator, and connected electrical loads.
Under normal conditions, utility power supplies the connected loads while the ATS monitors the incoming source. If utility power is interrupted, the transfer switch initiates the generator backup sequence and transfers the loads once generator power is available.
When the utility source returns, the RDT automatically retransfers the electrical load to utility power and allows the generator to shut down according to its programmed operating sequence. This provides hands-free backup-power operation.
200A, 240V Configuration
The RDT-CFNC-0200A-QS7 is rated at 200 amps, 240 volts, 60 Hz, with a single-phase, 2-pole, 3-wire configuration. Kohler's technical documentation identifies the configuration as having a solid neutral and a NEMA 3R enclosure for the aluminum version.
This configuration is intended for installations where the existing electrical distribution system can accommodate the transfer switch without requiring an integrated load center.
MPAC 500 Controller
The MPAC 500 microprocessor-based controller manages the transfer switch's automatic operating sequence. It provides status information through the switch's indicator system and coordinates transfer and retransfer functions.
The RDT includes source-available and position-indicating LEDs, along with a common/fault relay. An accessory board with an audible alarm and an external alarm module are available as optional equipment.
Load Management
The RDT supports load-control time delay and offers optional load-shedding capability. These functions can be useful when generator capacity needs to be managed during an outage.
Load shedding can help prevent selected electrical loads from being energized when generator capacity is insufficient for the total connected demand. The appropriate load-management strategy depends on the generator capacity and the electrical loads being backed up.
Durable Aluminum Enclosure
The standard RDT-CFNC-0200A-QS7 uses a corrosion-resistant aluminum enclosure and is suitable for indoor or outdoor installation. Its enclosure is designed for installations where protection from normal outdoor environmental exposure is required.
The enclosure also provides a relatively compact solution for integrating the transfer switch into an existing electrical system.
Generator Compatibility
Kohler specifies this 200A RDT model for use with single-phase KOHLER residential and small-business generators. This makes generator and ATS compatibility an important consideration when selecting the correct system components.
The RDT is distinct from the RXT series: the RDT uses the MPAC 500 controller, while the comparable RXT residential models are designed around KOHLER generators equipped with RDC2 or DC2 controllers.

Ideal Applications
The Kohler RDT 200A ATS is well suited for:
- Residential standby generator systems
- Small-business backup power
- Whole-building standby applications
- Existing electrical installations being equipped with generator backup
- Essential-load backup systems
- KOHLER single-phase generator installations
- Applications requiring automatic utility/generator transfer
Standard Model vs. Load-Center Version
Kohler also offers a closely related 200A RDT model with an integrated load center, so the model number should be checked carefully before ordering.
| Feature | Standard RDT | RDT with Load Center |
|---|---|---|
| Model | RDT-CFNC-0200A-QS7 | RDT-CFNC-0200B-QS7 |
| Rating | 200A | 200A |
| Voltage | 240V | 240V |
| Phase | Single phase | Single phase |
| Load Center | No | Yes |
| Controller | MPAC 500 | MPAC 500 |
| Enclosure | Aluminum | Aluminum |
| Approx. Weight | 15 lb. | 18 lb. |
| Approx. Dimensions | 24.1 × 13.4 × 7.0 in. | 36.1 × 16.4 × 7.0 in. |
The load-center version is a separate model and is substantially larger, so it should not be substituted based solely on the shared 200A/240V rating.
Installation Considerations
The RDT is electrical distribution equipment and should be installed by qualified electrical personnel in accordance with applicable electrical codes and Kohler installation documentation.
Before purchasing, verify the:
- Generator model and compatibility
- System voltage and phase
- 200A service/load requirements
- Number of poles and wires
- Need for a load center
- Required enclosure configuration
- Available fault current
- Load-shedding requirements
- Local code and installation requirements
Kohler also offers service-entrance versions of the RDT. The service-entrance models have different configurations, dimensions, and installation requirements from the standard RDT-CFNC-0200A-QS7.
Why Choose the Kohler RDT 200A ATS?
The Kohler Power RDT Series 240V 200A Automatic Transfer Switch provides an automatic and coordinated method of switching electrical loads between utility and standby generator power. Its 200A capacity, 240V single-phase configuration, MPAC 500 controller, status indicators, load-management options, and corrosion-resistant aluminum enclosure make it a practical choice for compatible KOHLER standby generator systems.
For installations that do not require an integrated load center or service-entrance configuration, the RDT-CFNC-0200A-QS7 offers a straightforward standard-transfer configuration for automatic backup-power management.
Model identification: The specifications above refer specifically to the RDT-CFNC-0200A-QS7. Kohler also sells 200A RDT models with a load center and service-entrance configurations, so the complete model number should be verified before purchase.
