Plug'n Play

         Electronic trip units are normally supplied factory fitted. However spares are available that can be simply plugged in to breakers installed in the field. Each trip unit then needs to be adjusted to the required settings. If the installation is not powered up the installed battery pack or the separately available test kit with Power Pack can be used as alternate power source.
