Trip Unit Comparison
The table below lists the standard (X) and optional (O) trip unit features for Trip Unit types Standard, Ammeter, Power, Harmonic and MicroLogic X/Xi for use in Power-Zone 4 Switchgear. If the feature is tagged in the table with the letters "DM" then that indicates that a separate MicroLogic X Digital Module must be selected in order to get that specific trip unit functionality (see Upgrade with Digital Modules).
