The 385 relay is a mechanically latched, electrically reset relay. It can be furnished with two, four or six sets of double throw contacts. The molded, plastic dust cover snaps onto a standard DIN rail as well as incorporating mounting slots for panel mounting. The 385 does not have a dominant coil. If both coils are energized at the same time, all of the normally open contacts close and all normally closed contacts open. If one coil, (Coil A) is de-energized, then the contacts on the opposite side (Coil B) will not transition until coil power is restored to the first coil (A).
