"In applications which involve lengthy duty cycles, the preferred configuration would be the use of the form B or N.C. contacts for long term duty. In those instances where the form A contact is held closed for extensive time periods, coil heating will increase contact "T" rise and may result in shorter than optimum life. Alternately, latching types may be considered for these applications, using a storage capacitor to "Reset" the relay on power-down."
