30-2000 amp, 2 & 3 pole
with generator exerciser
and Service Entrance Disconnect

 

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  

Product Features:

* Suitable for use as service entrance equipment.
* The ASCO Series 300SE is listed to UL 891 standard for Dead-Front Switchboards, and meets
   all NEC requirements for service entrance equipment.
* Automatic Transfer Switch is listed to UL 1008 for total system loads.
* Sizes available from 150 through 3000 amps.
* Available to 600 VAC, 50 or 60Hz, single or three phase.
* Circuit Breaker disconnect on the normal for isolation of transfer switch and other electrical equipment.
* Disconnect link on Neutral and Ground.
* Silver plated copper ground and neutral bus.
* Solderless screw type terminals for External Power Connections.
* Ground fault trip protection provided on sizes of 1000 amperes and above.
* UL approved Type 1 enclosure.
* Available with solid or switched neutral.
* Optional TVSS Available on Normal, Emergency and /or Load.

Microprocessor Controller

The ASCO Microprocessor Controller is used with all sizes of Power Transfer Switches. It represents the most reliable microprocessor controller in the industry and includes, as standard, all of the voltage, frequency, control, timing and connectivity functions required for most emergency and standby power applications.

The easy-to-read flush-mounted control and display panel provides LED indicators for switch position and source availability. It also includes test and time-delay bypass switches
