ASCO 185 Series SE Rated Automatic Transfer Switch
The ASCO 185 Series 100A Automatic Transfer Switch is a compact, service entrance rated solution designed for smaller residential standby power systems. It’s ideal for homeowners who want a dependable, automatic way to switch between utility power and a backup generator during outages—without manual intervention or hassle.
This model is compatible with all 2-wire start generators, offering broad system flexibility across leading generator brands. With a 100-amp rating, it’s perfect for essential load coverage or for smaller homes and cabins where full-service backup isn’t required. Its NEMA 1 enclosure is designed for indoor installations, making it well-suited for garages, basements, or dedicated electrical rooms.
As a service entrance rated unit, the 185 Series includes a built-in main circuit breaker, eliminating the need for a separate service disconnect and simplifying code-compliant installations. It constantly monitors utility power and automatically starts your generator during outages. Once utility power is restored, it transfers the load back safely and shuts the generator down after a cool-down cycle. A built-in weekly exercise feature keeps your generator system active and reliable.
If you’re upgrading an outdated manual switch or installing a new generator system, the ASCO 185 Series 100A ATS provides dependable protection and peace of mind. Request a quote online today.
