DACN10 AC surge protector is used for the 'secondary' protection of the single-phase networks against the surge voltages creating by lightning. DS98 is equipped with an internal thermal safety which will disconnet the unit from the AC network in case of end of life. Regarding the failsafe mode this surge protector is equipped with the option of disconnection and AC line cut-off. This disconnection will be indicate by the turn on of the red led in the front. Very compact, the DACN10 surge protector must be installed close by the equipment to protect, downstream a 'primary' surge protector. DACN10 provides both a common and differential mode protection.
