Protection against closing short-circuit “MCR” 5. the case where the presence of current determined with the circuit-breaker the "OPEN" state, state error signaled warning message being displayed (see par. 13.. Protection against undervoltage “UV”; 10.4 Description inputs/outputs 13. Protection against instantaneous short-circuit high currents inst"; 7. When the circuit-breaker opens, the page with the "Trip" data displayed (when Test" pressed, automatically the presence Vaux).2. A timing indication (message "alarm" LED) provided the unit's display, which activated during protection alarm.6 Protection functions The PR123/DC protection unit carries out independent protection functions. +90°C Relative humidity . +70°C Storage temperature -40°C .2 Auxiliary power supply The external auxiliary power supply provided using galvanically-separated power pack.4. External system bus, RS485 physical interface, Modbus RTU protocol, baud rate 9600-19200 bps. Protection against short-circuit with adjustable delay “S” and "S2"; 3. Test bus front test connector.2. The characteristics the power pack are given the table below: Characteristics Version PR123/DC Auxiliary voltage (galvanically separated) 24V ±20% Maximum ripple 5% Inrush current 24V ~10A for 5ms Rated power 24V ~5W 13..6) and the "warning" LED lighting up. 13.2.1 Circuit-breaker state The PR123/DC unit records the state the circuit-breaker means specific wiring the circuit-breaker.5 Communication bus Local internal bus rear connector; RS485 physical interface, Modbus protocol. Protection against overvoltage "OV"; 11. The signal can combined with relay the PR120/K module with those the PR021/K unit.2. The presence the auxiliary power supply enables the relay unit used even with the circuit-breaker open, well powering all the modules, with the exception the PR120/V-PR120/LV MEASURING module, which powered means connection the busbars.1. 14.2. Model 3447 A pparatus Emax DC S cale D 1SDH000635R0002 Page No. 13..2.4.2.. Override protection when release not powered.5mA.2. Protection against earth fault with adjustable delay “G”; 6.13. Protection against overload with inverse time “L”; 2. 98% with condensation Degree protection (with PR123/DC installed the CB) 30 13. 13. Protection against overtemperature "OT"; 9.3 Environmental characteristics Operating temperature -25°C . particular: 1.2 Binary outputs - K51/SZout (K51/DFout): Zone selectivity: output for protection (only with Vaux) - K51/GZout (K51/DBout): Zone selectivity: output for protection (only with Vaux) Note: These inputs/outputs can used between PR122/PR123 series units only. 13. 50/1 08 .1 Binary inputs - K51/SZin (K51/DFin): Zone selectivity: input for protection (only with Vaux) - K51/Gzin (K51/DBin): Zone selectivity: input for protection (only with Vaux) 13.1 Powered the PR120/V-PR120/LV module For full explanation the features the PR120/V-PR120/LV, see par. Protection against phase unbalance “U” ; 8. Protection against reverse active power "RP"; 12. disabled when the alarm condition ceases when the protection has been tripped.. Protection against instantaneous short-circuit “I”; 4.2. A Since the auxiliary voltage needs isolated from the ground, "galvanically separated converters" accordance with the IEC standard 60950 (UL 1950) the equivalent IEC 60364-41 and CEI 64-8 have used guarantee current in common mode leakage current (as defined IEC 478/1 and CEI 22/3) greater than 3..6.2
