Transfer Switches

30 to 3000 Amps transfer switches with field-selectable voltage settings for utility-to-emergency power transfer. Engineers and Contractors trust the ASCO 300 SERIES for code-compliant performance in commercial and light industrial applications.

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 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 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.

For Customized Mission Critical Applications Create exactly the power control solution you want with a variety of configurable modules. The modules reduce lead and delivery times, and facilitate installation and start up, so customize a system to your requirements and still meet tight deadlines.

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.

Automatically transfer loads between sources with bypass isolation features to allow inspection, test, and service without power interruptions and provide redundant automatic transfer functionality. ASCO 7000 SERIES Electrically Operated 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. The electrically operated bypass switch also provides redundant automatic power transfer if the ATS is disabled or removed from service.

For Commercial or Light Industrial Use When power fails, businesses suffer. For some organizations, a permanent generator is too costly. Instead, a permanent means for quickly connecting a portable or temporary generator can make economic sense. Installing a manual transfer switch and a connecting means can provide an adequate and cost effective solution. This equipment can provide access for an alternate power source when a generator malfunctions or is removed from service for maintenance.

For Mission Critical Applications 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.​

ASCO 300 SERIES Dual Purpose Quick Connect Power Panel The SERIES 300 Dual-Purpose Quick Connect Power Panel is the singular solution for connecting load banks for testing and providing "backup-for-the-backup" according to NEC 700.3 requirements. These Load Bank Docking Stations are available in models ranging from 150 to 4000 Amps, they are designed to provide years of trouble-free service.

Configurable with optional breakers for Backup Power on Optional Standby Systems or a Permanent Generator The ASCO 300 SERIES manual transfer switch with integrated quick-connects provides a means for quickly connecting a portable or temporary generator to a building’s electrical system to provide backup power, or to provide a “backup to the backup” when servicing an off-line engine-generator.

For Customized Mission Critical Applications The ASCO Automatic Transfer Switchboard contains two ASCO 2000 ampere automatic transfer bypass-isolation switches, with circuit breakers on the normal and load side of each switch. An ammeter and voltmeter are also located on the load side of each switch.

For Customized Mission Critical Applications The ASCO Service Entrance Rated transfer systems are designed for automatic switching of loads between the utility source and an alternate source of power.

For Customized Mission Critical Applications Control logic for selecting between the alternative power sources. Normal, emergency, and/or load circuit breakers Protective relaying (as required) Optional instrument meters for normal, emergency, or load for local monitoring.

SourcePacT provides a way to streamline and maximize the value of any BESS deployment with its simplified design and increases sustainability by prioritizing cleaner energy. Isolation & Interconnect Switches provide the necessary controls, metering, and switching needed to connect a local power island (critical loads & DER) to larger power infrastructure. This allows the DER (Distributed Energy Resource) to operate as a grid interactive device when connected to the larger electrical system but switch to grid forming by isolating the island during a power anomaly.
