Automatic Transfer Switches 1-Phase 2-Pole 30-400 Amp

The ASCO Series 300 Automatic Transfer Switches 1-Phase 2-Pole 30-400 Amp was designed for one purpose–to automatically transfer critical loads in the event of a power outage. Available with NEMA 1, NEMA 3R, NEMA 4 and NEMA 12 enclosures.  Each and every standard component was designed by ASCO engineers for this purpose. The rugged construction and proven performance of the ASCO Series 300 assure the user of many years of complete reliability. The Series 300 is even designed to handle the extraordinary demands placed on the switch when starting or restarting stalled motors and switching high inrush loads. ASCO’s Series 300 modular, compact design makes it easy to install, inspect and maintain. All parts are accessible from the front so switch contacts can be easily inspected.
