Differential switch type A

Differentials that guarantee the same protection as those of the AC type, but in addition they are able to guarantee protection even in the presence of alternating fault currents with unidirectional pulsating components. These devices are widely used in the tertiary / industrial sector, in systems with electronic equipment capable of generating dangerous continuous components. Ideal in the use of users with electronic devices and in the prevention of untimely interventions due to overvoltages caused by non-direct lightning strikes, overvoltages dependent on operations on the electricity network.
