Energy storage relay
ESR 1
Mechanical contactors can be kept in switched state at no power by using a mechanical latch. This energy saving operation is not generally applicable. For example, if a contactor has to fall back automatically to off-state when the mains fails, a mechanical latch is not yet applicable.
The ESR 1 generates a switch-on pulse and stores energy. Thus, it can bring a contactor not only in the mechanical latch, but also disconnect this mechanical latch automatically, when mains fails.
