load distribution panel, and protective transient voltage surge suppression for normal and emergency operation. It is available in 200 or 400 amp rating, single phase or three phase, with solid or switched neutral.
The ASCO 300L will reliably transfer business-critical loads to emergency sources, protecting hospitals, shopping malls, commercial buildings, cell sites, and more 24/7/365. Commercial/Retail – An electrical power failure can slash the profits of any facility catering to consumers by forcing emergency closures and potentially destroying climate-controlled inventory. The ASCO 300L solution can help prevent these disasters. Healthcare/Hospital – A majority of healthcare facilities rely on ASCO for emergency power and peace of mind. ASCO’s technological leadership helps create integrated emergency power systems that better equip healthcare facilities operations and engineering staffs to meet the requirements of NFPA 110 and NFPA 99. Telecom – A power outage can bring down a cell site, interrupting service that results in delayed emergency response, lost revenue, and disgruntled customers who may switch carriers. The ASCO 300L is a cost-effective, customizable solution to ensure each tower remains up and operational. The ASCO S eries 300L PTLC has everything to protect sensitive loads from power outages in a variety of commercial and light industrial facilities. It features a world-class ASCO S eries 300 Automatic Power Transfer Switch with microprocessor digital controller, with normal and emergency circuit breaker disconnects, versatile Square D
For facilities requiring greater reliability, ASCO can design three-source systems with the ASCO SERIES 300L to provide a second alternate power source to back up the first if it fails. Upon the loss of the utility power source, the system provides all necessary controls to start both alternate power sources. Critical loads are automatically or manually transferred to the first alternate or preferred power source that achieves acceptable voltage and frequency. When normal power is restored, the controls automatically re-transfer the load to the utility power source. • Standard version is manual transfer between alternate sources • Auto start and auto transfer to first alternate source is special ACC IIIA ASCO provides more than leading edge technology. ASCO Support has seasoned teams with decades of expertise who satisfies customer requirements for standard or custom designs to help move a project from conception to completion, and on-going operation. ASCO Services, the largest power switching and controls service unit of its kind in the country, is dedicated to serving customers, 24/7/365. Highly trained and EGSA-certified service technicians quickly respond to any customer need, from commissioning a new project and upgrading legacy Backup for your backup
