Latching Two-Position Types —
Except for the latching feature, MDR
latching relays utilize the same general
construction as non-latching types. They
have two sets of coils and provide a
latching two-position operation.
The above AC contact ratings are
based on contact loads having a
50% power factor. The DC contact
ratings are based on resistive loads.
