Operation principle

The 1728 relay is a specially designed "'fast action relay" equipped with 4 x 10 A CO contacts. The basic design is made of two relays included in one relay dust cover :

- one 1804 relay giving fast action < or = 4 ms of the 4 NO contacts (qualified EDF HN 45S25 cl. 2a)

- one 1783 relay, with magnetic arc blowing, for heavy contacts characteristics (breaking capability) - qalified EDF HN 45S25 cl. A1.
