100 Amp Transfer Switches ASCO 185 Series

The Service Entrance Rated ASCO 100 Amp Generator Transfer Switch serves the main circuit  breaker panel with power from the utility or generator. During a power outage, the 100 Amp Automatic Transfer Switch isolates the utility from the main panel and connects the panel to the generator. Power is available to all circuits served by the main circuit breaker panel. The NEMA 1 Steel cabinet is suitable for indoor installation.

100 Amp Automatic Transfer Switch

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

Compatible with any two-wire start system, The 100 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 from the subpanel and supplies generator power to the home or business.
