#RA400 NSE A050W633 RA Series automatic transfer switches integrate with Cummins RS generator sets. The RA412N3 is a 2-Pole, 400 Amp Automatic Transfer Switch for 120/240-Volt single phase installations. This switch is not service entrance rated. The RA412N3 transfer switch monitors utility power 24 hours a day, 7 days a week. When utility power becomes unsatisfactory or fails, the transfer switch signals the generator set to start, then automatically transfers the load when the generator is ready. When stable utility power returns, the transfer switch automatically switches the electrical load from the generator to the utility. No action is required by the homeowner. RA series automatic transfer switches are UL-1008 listed and suitable for use in standby power systems for residential and light commercial applications.
