Bypass isolation power
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.
