ATyS C is a 4-pole automatic transfer switch with positive break indication, ensuring safe and reliable source switching. It is suitable for both mains-to-mains and mains-to-generator applications. In automatic mode, the switch continuously monitors two power sources and performs an on-load transfer based on settings configured through the built-in DIP switches. Designed for low-voltage power distribution systems, it supports applications where a brief interruption of the load supply during source transfer is acceptable. Additionally, the ATyS C offers remote monitoring capabilities through RS485 communication for enhanced system supervision.
