ASCO SERIES 300 Service Entrance Manual Trans. Switch
For Commercial or Light Industrial Use.
When power fails, businesses suffer. For some organizations, a permanent generator is too costly. Instead, a permanent means for quickly connecting a portable or temporary generator can make economic sense. Installing a manual transfer switch and a connecting means can provide an adequate and cost effective solution. This equipment can provide access for an alternate power source when a generator malfunctions or is removed from service for maintenance.
ASCO 7000 SERIES Service Entrance Transfer Switch
For Mission Critical Applications.
Our line of ASCO 7000 SERIES Service Entrance Power Transfer Switch combines automatic power switching with a disconnect and overcurrent protective device on the utility source. These are typically installed at facilities that have a single utility feed and a single emergency power source.
Manual transfer switches
Manual transfer switches are the simplest means of transferring load between power sources. With break-before-make switching sequences, these switches cost-effectively transfer loads between utility and backup power sources. They enable homes, commercial businesses, and industrial facilities to make the most of their resources and connect to temporary or supplemental generators. ASCO Manual Transfer Switches offer robust features that help prevent facilities from sacrificing productivity lost to power interruptions. Browse the ASCO Manual Transfer Switch range below.
