ATyS bypass Single Line enclosures ensure automatic switching to the available source in case of power failure. This ensures continuity of power supply, human safety and critical loads such as sprinklers, lifts, water pumps, etc.
In addition, they ensure continuity of service during inspection, maintenance and testing operations, as well as complete isolation of the automatic transfer switches for safe intervention without load interruption.
The ATyS Bypass Single Line version can be used to bypass the priority source.
