Automatic transfer switches

For Mission Critical Applications ASCO 7000 SERIES Automatic Transfer & Bypass-Isolation Switches are available in open transition, closed transition, and delayed transition designs. The bypass and isolation features allow the primary automatic transfer switch to be inspected, tested, and maintained without interrupting power to the load. They also provide redundant power transfer if the ATS is disabled or removed from service.

For Mission Critical Applications ASCO Power Transfer Switches are the standard of the industry. High speed transfer of loads between alternate sources of power, regardless of ampacity, is achieved using a reliable, field-proven solenoid operating mechanism. When combined with a programmable microprocessor controller with keypad and LCD display, they offer the most advanced method of transferring all types of loads, such as motors, electronic drives, UPS’s and microprocessor-based systems.

For Mission Critical Applications 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.

For Commercial or Light Industrial Use 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.​​

For Residential or Light Commercial 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.
