AUTOMATIC TRANSFER SWITCH CONTROLLERS
 

The ATL automatic transfer switch controllers are used for the automatic switching of the load from the MAIN line to a stand-by or emergency SECONDARY line and vice versa.
They are composed of a single unit in an insulated housing and have two outputs for the "automatic and/or manual" control of contactors or motorised circuit breakers.
  
Selling points
- Supervision of two three-phase supply lines
- Supervision for emergency demand of generating sets
- Supervision of motorised circuit breakers
- Event log
- TRMS voltage measures
