ASCO 3ATS 30-400A 3-Phase 4-Pole Automatic Transfer Switches

The ASCO 3ATS 30-400A 3-Phase 4-Pole Automatic Transfer Switches were designed for one purpose, to automatically transfer critical loads in the event of a power outage. These switches are designed by credible ASCO engineers for this purpose. Timeless rugged construction and proven performance of the ASCO SERIES 300 assure the user of many years of complete reliability.

The ASCO 3ATS 30-400A 3-Phase 4-Pole is even designed to handle the extraordinary demands placed on the switch. These demands come in 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.
