Service Entrance Rated for Simplified Installation
The service entrance rated design means this transfer switch can serve as your main electrical disconnect, eliminating the need for a separate service panel and reducing installation complexity and costs. This streamlined approach is ideal for new construction, electrical service upgrades, or generator system retrofits, providing a clean, efficient electrical infrastructure solution.
Automatic Power Transfer for Mission-Critical Operations
When utility power fails, the RTSW200K3 instantly detects the outage, signals your Generac standby generator to start, and automatically transfers your electrical load to backup power once the generator reaches stable operating voltage. When utility power returns, the system seamlessly transfers back and signals the generator to shut down after a proper cool-down period—all completely automatic with no operator intervention required, ensuring continuous operation of critical systems.
Seamless Generac Generator Integration
The RTSW200K3 is designed to work flawlessly with Generac's complete line of industrial standby generators. The transfer switch communicates directly with your generator, coordinating startup sequences, monitoring readiness, managing load transfer, and controlling shutdown procedures—ensuring reliable, coordinated operation of your entire backup power system.
Built for Reliability in Demanding Environments
Housed in a NEMA 3R weatherproof enclosure, this transfer switch is engineered for outdoor installation and long-term reliability in harsh industrial weather conditions. Generac's proven industrial-grade transfer switch technology ensures dependable performance when your facility needs it most, with robust components designed for thousands of switching cycles over decades of service.
Professional Installation Required
This service entrance rated transfer switch must be installed by a licensed electrician familiar with high-voltage three-phase electrical systems and local electrical codes. Professional installation ensures safe, code-compliant operation and proper integration with your Generac standby generator system.
Protect your industrial operations and production continuity with reliable high-voltage backup power technology built for demanding environments.
