Upgrade for AGR-31B Protection RelayMORE MONITORING FEATURESThe new AGR-31B “H” ensures optimium monitoring and performance.Safe ModeA safe mode can be enabled during switchboard maintenance. Two independent INST thresholds can be saved in on-board memory.The user can toggle INST settings quickly via the LCD menu or over the data communication link. A lower INST threshold will reduce theincident arc energy. Settings can be quickly returned to normal after maintenance to provide optimum performance.Accurate SettingOverload protection settings can be matched exactly to the circuit needs. LTD current threshold settings can be fine-tuned to the nearestAmpere.New AlarmsUnder/over-voltage; under/over-frequency. Take action automatically if these parameters go outside your acceptable limits. Voltfree output contacts included. AVAILABLE AS AN OPTIONAL EXTRA FEATURE OF AGR-31B.-.H.HarmonicsHarmonic current measurement. Identify loads causingharmonic pollution, optimise harmonic filtering and ultimatelysave money with this new feature. Monitors individual harmoniccurrents per phase at each harmonic order. INCLUDED ASSTANDARD WITH AGR-31B.-.H.

TemPower 2 Air Circuit Breakers5 Reasons to use TemPower 2 ACBsEfficient air convectionthrough a pressure valve1. Patented High Performance 5000A and 6300A ACBsThe air circuit breaker interrupts the current at two points on the lineside while dissipating heat from contacts or terminals by efficient airconvection through pressure valve.2. Double opening and closing coilsDouble Opening and Closing Coils provides extended control systemredundancy to an ACB. Double coils allow designers to implementback-up tripping and closing systems. It provides the end-user withultimate reliability on critical UPS circuits connected to critical loads.3. Fast interruption by unique “Double Break” system*The unique “DoubleBreak” main contact system ensures extremelyfast interruption of short circuit currents and substantially reducesmain contact wear. The internally symmetrical “DoubleBreak” structuremeans the moving contact is isolated from the supply voltage evenwhen the ACB is reverse connected. TemPower 2 ACBs up to 4000Ause DoubleBreak technology.pressure valveCUSTOMER ENDORSEMENT“The performance of Terasaki’s ACBs wasproven on site when a main busbar failed in oneof the switchrooms. The ACB was reclosed onthe short-circuit fault twice during fault diagnosisand is still in operation following a service byTerasaki.”Andy Oswald, BAA(Airport Operating Company, UK)4. Easy MaintenanceThe unique design of TemPower 2 incorporates its isolating clusters andmain contacts on the ACB body. The main contacts and isolating clustersmay be maintained without having to isolate the switchboard.5. Replacement of the main contacts*The fixed and moving contacts can easily be replaced in the field, thusprolonging the life on the circuit breaker. Changing each pole takesaround 15 minutes.*Not available on AR68 TemPower 2 Air Circuit BreakersHeathrow Airport Terminal 5

Protection FeaturesOverload ProtectionReverse power trip function (S-characteristic)Adjustable from 40-100% of rated current. Thermal memory isavailable on the AGR21B.31B.This feature provides additional protection when parallelinggenerators. The AGR22B/31B protection relay for generatorprotection with the reverse power trip function , negates the needfor installation and wiring in an external reverse power relay. Thisfeature is available using an AGR protection relay with a generator“S” type characteristic only. (ANSI-32R)Two channel pre-trip alarm function (optional)This function can be used to monitor critical circuits. Forexample, the function can be set so that when a pre-trip alarm isactivated, non-essential loads can be switched off. This featureis only available on AGR22B/31B protection relay models with agenerator “S” characteristic.Negative Sequence Current Protection FunctionIn 3-phase, 4 wire systems that contain harmonic distortion,large currents may flow through the neutral conductor. TheN-phase protection function prevents the neutral conductorfrom sustaining damage or burn-out due to these large currents.(ANSI-46).Ground fault trip functionThis function eliminates external relays to provide a ground faultprotection to TN-C or TN-S power distribution systems on theload side. Ground fault protection on the line side (restrictedearth fault) is also available as an option.Earth leakage trip functionUsed in conjunction with Zero phase Current Transformer (ZCT),this function provides protection against leakage to earth of verysmall levels of current. Trip or alarm indication, and contactoutput is available to enhance the level of system protection.Phase rotation protection functionThis function detects the negative-phase current occurring due toreverse phase or phase loss and prevents burnout of a motor ordamage to equipment.Advanced LCD display, Protection RelayThe AGR-31B protection relay comes standard with the backlitLCD display.
