400 Amp Transfer Switches ASCO 185SE Series

The Service Entrance Rated ASCO 400 Amp Generator Transfer Switch powers your essential and critical loads through the main circuit breaker panel. During a power outage, the 400 Amp Transfer Switch isolates the utility power from the main panel and connects generator  power to main panel. All critical, essential, and convenience loads within the main circuit breaker panel receive power. The NEMA 1 steel cabinet meets code for indoor installations only.

400 Amp Automatic Transfer Switch

ASCO Transfer Switches make sure the power stays on when utility power fails. When utility power returns, the ASCO ATS switches the home or business back to utility power and begins generator cool-down.

Compatible with any two-wire start system, The 400 Amp Automatic Transfer Switch monitors the utility power 24/7. When an outage occurs or power quality falls below an acceptable level, the transfer switch starts the generator and waits as the engine warms and the speed stabilizes. Once the generator is ready, the ATS isolates the utility and supplies generator power to the home or business.
