Automatic Transfer Switches
Automatic transfer switches (ATS) are critical components of any emergency or standby power system. Transfer switches are reliable, rugged, versatile and compact assemblies for transferring essential loads and electrical distribution systems from one power source to another.
Eaton’s family of automatic transfer switch controllers and remote annunciators bring advanced intelligence, supervision and remote management capability to a comprehensive automatic transfer switch product line offering.
The Eaton Breaker Type Bypass Isolation Switch is designed to require minimum maintenance even under the most strenuous of operating conditions. Due to the use of moulded case switches and their inherent self-protection capability, the contact structure and mechanism is extremely long lived.
Eaton’s bypass isolation contactor type automatic transfer switches include dual automatic switching mechanisms that provide redundancy for critical applications. The ATS distributes electrical power to the load, while the automatic bypass serves as a back-up. When the ATS is isolated for test, power is routed through the automatic bypass switch to ensure that critical loads remain powered without interruption.
Eaton’s bypass isolation power frame type automatic transfer switches (ATS) are designed for mission-critical systems where redundancy is required, allowing maintenance, inspection and testing to be performed while maintaining constant power to the load. Designed for applications where total system coordination is desired, they offer integral overcurrent protection with an electronic trip unit.
Eaton’s contactor type automatic transfer switches (ATS) are designed to quickly and reliably transition critical loads between preferred and alternate/generator power sources. Ideal for use in NFPA 70 emergency, legally required, optional standby and critical operations systems that demand reliable performance.
Eaton’s moulded case type automatic transfer switch, with self-protecting main contacts, is designed to provide unmatched withstand close-on performance for standby power applications requiring open transition. Transfer switches can be configured with integral overcurrent protection and a service entrance rating.
Eaton’s power frame type automatic transfer switches (ATS) offer the highest amperage capacity in the industry. Designed for applications where total system coordination must be accomplished, they offer integral overcurrent protection with an electronic trip unit for a variety of standby power applications feeding critical and non-critical loads.
