Transfer Switch rated 3 Pole 2000 amperes shown in Type 3R secured double door enclosure with solid neutral

The ASCO Service Entrance Power Transfer Switch combines automatic

power switching with a utility circuit breaker as a disconnect device. The power transfer switch meets all National Electrical Code requirements for installation as service entrance equipment.

Service entrance rated transfer switches generally are installed at facilities that have a single utility feed and

a single emergency power source. A circuit breaker serves as the utility disconnect

and links are provided to connect both neutral and ground conductors.

The ASCO 300SE Service

Entrance Automatic Transfer Switch uses the same reliable transfer switching mechanism and controller as the series 300 product platform, and also includes a utility circuit breaker as

a disconnect device.
