ASCO 185 Series SE Rated 200 Amp Automatic Transfer Switch
The ASCO 185 Series 200A Automatic Transfer Switch is a dependable, service entrance rated solution for residential and light commercial standby generator systems. Designed to manage medium-load applications, this switch supports all 2-wire start generators and delivers reliable, hands-free transfer of power during outages. Whether you’re protecting your home or a critical business operation, the 185 Series ensures a smooth transition between utility and backup power sources.
This model features a NEMA 1 indoor-rated enclosure, making it ideal for basement, utility room, or indoor electrical panel installations. The integrated main circuit breaker eliminates the need for a separate service disconnect, simplifying installation and helping meet code requirements more efficiently.
The switch continuously monitors utility power and initiates generator startup when an outage is detected. Once power is restored, it automatically transfers the load back and initiates a generator cool-down sequence. A built-in weekly exercise function ensures your generator stays ready, with settings for loaded or unloaded testing.
Whether you’re upgrading an outdated ATS or installing a new backup power system, the ASCO 185 Series 200A offers safety, reliability, and compliance in one complete package. Ready to make the switch? Request a quote online today for pricing and shipping details.
