Applications

Healthcare

Healthcare facilities require uninterrupted power to
mitigate risks and ensure patients receive the best
possible care. When only a single permanent genera­tor provides backup power, the NEC® now requires a
means for connecting a portable generator. ASCO’s
SERIES 300 MTS can be used to switch loads to a
temporary power source when permanent generators
are o-line.

Telecom

Telecommunications facilities must provide a high level
of service and dependability. Lost power could disrupt
critical services to customers and businesses. The
ASCO SERIES 300 MTS provides a way to keep power
on and customers online.

Municipal

Communities rely on city and county governments for
critical emergency services. A power interruption can
hinder emergency response. The ASCO SERIES 300
Manual Transfer Switch enables connection to backup
power for critical services when they are needed
most. It also provides also cost-eective backup solu­tion for water and wastewater pump stations.

Commercial, Retail, Light Industrial

Power interruptions can profoundly impact the revenues
of retail, commercial, and industrial businesses. Outages
interrupt shopping, disrupt operations, and create safety
problems. They can result in lost transaction data, lost
account information, and damaged data equipment. Loss
of refrigeration can ruin inventory. The ASCO SERIES 300
Manual Transfer Switch provides a cost-ecient backup
power switching solution for small businesses.
