Intelligent Power Management Technology
Unlike basic transfer switches, the RTSW200G3 features smart load shedding technology that automatically manages power distribution during outages. This ensures your most critical systems—HVAC, refrigeration, security, communications, and essential equipment—stay online while optimizing your generator's fuel efficiency and runtime. The system intelligently sheds non-essential loads to prevent generator overload and extend operating time.
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.
Seamless Generator Integration
When utility power fails, the RTSW200G3 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 staff intervention required.
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 weather conditions. Generac's proven commercial-grade transfer switch technology ensures dependable performance when your business needs it most.
Professional Installation Required
This service entrance rated transfer switch must be installed by a licensed electrician familiar with 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 business continuity and revenue with reliable three-phase backup power technology.
