An electric device for an electric circuit having at least a first insulator with a first main insulating body and a second insulator with a second main insulating body. The first and second main insulating bodies protrude from corresponding portions of the electric device along a first longitudinal axis and a second longitudinal axis, respectively, with said first and second longitudinal axes lying parallel to each other in a common plane. The first insulator comprises at least a first insulating fin and at least a second insulating fin which protrude from the first main insulating body so as to lie in a respective first plane and a second plane, respectively, perpendicular with respect to said common plane. The first fin and the second fin have a first distance D 1 and a second distance D 2 , respectively, between their delimiting ends nearer to the second longitudinal axis and the first longitudinal axis, wherein D 1 > D 2 . The second insulator comprises at least a third insulating fin and at least a fourth insulating fin which protrude from the second main insulating body so as to face the first fin and the second fin, respectively. The third and fourth fins have a third distance D 3 and a fourth distance D 4 , respectively, between their delimiting ends nearer to the first longitudinal axis and the second longitudinal axis. The first, second, third and fourth distances D 1 , D 2 , D 3 and D 4 satisfy the following relationships: D 1 > D 3 ; D 4 > D 2 ; D 4 > D 3 ; and D 4 < D 1 + D 1 - D 2 .
