ASCO Series 300 Manual Transfer Switch

ASCO Series 300 Manual Transfer Switch is the perfect load transfer solution for commercial and municipal applications. The Series 300 Manual Transfer Switch can provide companies with a cost effective way to quickly connect a portable or temporary generator rather than buy a permanent generator. Installing a manual transfer switch and a connecting means can provide an adequate and cost effective solution. This solution can provide access for an alternate power source when a generator malfunctions or is removed from service for maintenance.

The Series 300 Manual Transfer Switch’s three-position center-off switch is robust and easy-to-use. It’s modular, compact design is easy to install and maintain and is designed to handle the demands of motors and high inrush currents
