General specifications of the electronic trip units include:• operation without the need for an external power supply• microprocessor technology• high precision• sensitivity to the true R.M.S. value of the current• trip cause indication and trip data recording• interchangeability among all types of trip units• setting for neutral configurable:– OFF-50%-100%-200% of phase setting for circuit-breakers E1, E2, E3 and E4/f,E6/f full-size versions, and E4-E6 with external neutral protection;– OFF-50% for standard E4 and E6.1The main performance features of the trip units are listed below.PR121ProtectionPR121/P PR121/P PR121/PPR122ProtectionPR122/PPR122/PPR122/PPR122/PRcFor all versionsUOTMNew modules available:Measuringopt.UVOV RV RP UF OFCommunicationSignallingBluetooth (wireless link)opt.opt.opt.PR123ProtectionPR123/PFor all versionsPR123/POT D U UV OV RV RP M UF OFNew modules available:Communicationopt.SignallingBluetooth (wireless link)opt.opt.ABB SACE 1/11
