ASCO 3AUS 1-PH 2-Pole 30-400 Amp Service Entry Rated Automatic Transfer Switch

The ASCO 3AUS 1-PH 2-Pole 30-400 Amp Service Entry Rated Automatic Transfer Switch combines automatic power switching with a utility circuit breaker as a disconnect device. This transfer switch meets all National Electrical Code requirements for installation as service entrance equipment. SER transfer switches are generally installed at facilities that have a single utility feed and a single emergency power source. A circuit breaker serves as the utility disconnect and links are provided to connect both neutral and ground conductors.

These switches use the same reliable transfer switching mechanism and controller as the SERIES 300 product platform. This ASCO 3AUS 1-PH 2-Pole 30-400 Amp Service Entry Rated also includes a utility circuit breaker as a disconnect device.
