Series 300SE Service
Entrance Power Transfer Switches
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
devic Made in USA
