ASCO 300 Power Transfer Switch Battle Card
Standard designs for commercial and light industrial facilities that are simple to procure, install, and commission.
Value Prop:
ASCO Transfer Switches make backup power possible. They enhance power availability by transferring electrical loads to alternate sources of power. From simple backup solutions to mission-critical facilities, transfer switches connect backup power to enhance safety and sustain operations.
Questions to Ask:
- Do you have a Generator?
- If so, do you have an existing switch?
- How old it is?
- Can we look at it?
- If yes, and in need of a Transfer Switch, ask the following:
Service Entrance, Non-Service Entrance, amperage, voltage, enclosure type, number of switched poles, open, closed or delayed transition, start up required?
Typical Applications
- Reliably transfer loads between two or more power sources
- Service and maintain equipment without disrupting power to loads
- Reduce equipment space requirements
- Transfer loads without impacting downstream equipment
- Add capability for a “backup-to-the-backup”
- Outpatient Healthcare Facilities
- Small & Midsize Businesses
- Light Industrial Applications
- Integrated & Stand-Alone Quick Connects
Transfer switch models differ by type of operation
Automatic
Automatic models switch loads to emergency power and back again whenever outages occur, without human intervention.
Non-Automatic
Non-Automatic models use operator initiated, local or remote electrical controls to transfer loads on command.
Manual
The simplest type, manual transfer switches require a person to operate a mechanical switching mechanism
Transfer Switch Components
- Enclosure
Available in a range of UL-rated types, rugged enclosures protect equipment and ensure promote reliability for a variety of indoor and outdoor environments.
- Transfer Mechanism
Electrically operated and mechanically held, solenoid-powered operating mechanisms reliably transfer load quickly for even the most demanding applications
- Controller
Electronic controller stores operating criteria, senses electrical conditions, executes trans-fer sequences, and tracks operational data.
- Communications & Metering
From simple indicators to remote annunciators, from real-time monitoring and control to interfacing building automation systems, communication features increase usability and system reliability.
