The amp hours describe the available capacity on a lead acid battery. The equation is broken down with the number before the Ah being divided by the hours printed on the battery. This yields the approximate power capacity the battery is able to maintain until it drains its power.
ABB offers. three-phase monitoring relays with selectable phase sequence monitoring. This provides the capability of ignoring phase. sequence conditions for applications, such as motors with forward and reverse rotation, where the phase sequence is. unimportant.
