Cummins 600 Amp ATS Automatic Transfer Switch

Cummins 600 Amp ATS Automatic Transfer Switch is a two-source switching device for 3-phase electrical systems, rated for up to 600 amps at 480 V or 277 V in a 3-phase, 4-wire configuration. It automatically detects power conditions and transfers connected loads between sources, enabling hands-off changeovers when the primary source changes or fails. This makes it suitable for commercial and industrial power distributions that require reliable automatic source switching to protect equipment and minimize downtime. Key specifications include a 600 Amp capacity, voltage options of 480 V and 277 V, and a 3-phase, 4-wire configuration. Typical applications involve standby power arrangements within 480 V/277 V, 3-phase networks where automatic transfer between sources is required to maintain continuous service.
