KIT ATCONTROL/R protectors cut off the power supply when they detect a permanent overvoltage or undervoltage, (for example, a fault in the neutral), thus protecting the equipment installed downstream.
Self-reclosing protector: when the permanent overvoltage comes to a halt, the protector reconnects the contactor.
Moreover, they also actuate when they detect a transient overvoltage, driving the current to earth and reducing the voltage to a level that does not damage the connected equipment. Tested and certified as protector Type 2 in official and independent laboratories according to standard EN IEC 61643-11.
It has a test button to check that installation has been executed correctly.
