Power Transfer Switches
Automatic transfer switches and non-automatic transfer switches

Reliably transfer business-critical loads to emergency sources with our line of industry-leading automatic transfer switches and non-automatic transfer switches. ASCO automatic transfer switches and non-automatic transfer switches from Emerson Network Power are applicable in many environments, ranging from residential, agricultural and light commercial applications to the critical power needs of healthcare, financial and data center facilities.

Get the advantage of having an emergency power system equipped by best-in-class technology with ASCO transfer switches. ASCO 7000 Series Power Transfer Switches are available in bypass-isolation configurations to allow testing of the switch without interrupting power to the load. When an integrated solution is required, ASCO Power Transfer Load Centers are available in configurations that can include a transfer switch load panel, circuit breakers and voltage surge suppression pre-wired in a compact package. 

Ensure the reliable operation of ground fault protection systems and reduction of voltage transients from unbalanced load switching with Emerson Network Power's line of ASCO non-automatic and automatic transfer switches. The ASCO 7000 series power transfer switch features switched or overlapping neutral options. This product is available in the conventional, two-position transfer configuration, plus closed or delayed transition modes of operation.
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.
Synchronize and parallel two independent power sources without interrupting power flow with our ASCO 7000 Series Soft Load Power Transfer Switches. The switch can be programmed to either maintain parallel operation of both power sources, or transfer the load to the onsite generating unit, avoiding transients caused by block loading.
ASCO protects medium voltage loads by offering maintainable and highly proven power transfer switches. The switches can be configured with protective relays and other options to meet specific project requirements.
Transfer loads between alternate sources of power regardless of ampacity size efficiently with ASCO 4000 Power Transfer Switches made possible with reliable, field proven solenoid operating mechanisms. Combined with programmable microprocessor controllers, they offer the most advanced method of transferring loads.
Automatically transfer critical loads in the event of a power outage with the ASCO Series 300. Rugged construction and proven performance assure the user of many years of reliability.
The ASCO Service Entrance Power Transfer Switch combines automatic power switching with the necessary disconnecting, grounding, and bonding required for use as service entrance equipment. The power transfer switch meets all National Electrical Code requirements for service entrance use.
Get all the intelligence your optional standby system needs to make sure power stays on when the utility fails, with ASCO Series 185 Power Transfer Switches.  When utility power has been restored, this line of power transfer switches will automatically transfer your loads back to utility and shut down the generator, saving fuel and standing ready to address the next utility failure.
The ASCO Series 185SE Service Entrance Automatic Transfer Switch uses the same reliable transfer switching mechanism and controller as the Series 185 product platform, and also includes a circuit breaker as a utility source disconnect device.
The ASCO 185L Power Transfer Load Center is a completely integrated package which incorporates the Series 185 Automatic Transfer Switch with microprocessor controller. A Square D load distribution panelboard with utility and generator disconnect breakers. And optional transient voltage surge suppression for protection of load circuits.
The ASCO 185P Standby Transfer Load Center is a completely integrated package suitable for Residential applications. The 185P incorporates the Series 185 Automatic Transfer Switch with microprocessor controller. A Square D QO Load Center to accept branch circuit devices. And optional transient voltage surge suppression for protection of loads.
