ATyS A is a 4-pole automatic transfer switch featuring positive break indication for enhanced operational safety. It is designed to support both mains-to-mains and mains-to-generator applications. In automatic mode, the switch continuously monitors both power sources and performs an on-load transfer based on parameters configured through the integrated DIP switches. It is intended for low-voltage power distribution systems where a short interruption of the load supply during the transfer process is acceptable.
