Monitoring, Controlling And Switching With SIRIUS Relays - Electromatic

for mounting on 3RT2 contactorsThe electronically delayed auxiliary switches for mounting onto contactors are dimensioned for contactor coilvoltages from 24 to 240 V AC/DC (wide voltage). Auxiliary switches for control and status signals are employedespecially for the switching of very small signals for electronic applications. They are used for example for pumpor fan run-on similar to OFF-delay timing relays or the delayed switch-on of a gate drive. Both the electrical andmechanical connection are realized by simply snapping the device on and locking it. A varistor is integrated inthe time-delayed auxiliary switch for the attenuation of switching overvoltages in the contactor coil.ApplicationON-delay For example for the delayedreadiness signaling of a driveafter start-up with centrifugal massOFF-delay Generation of run-on functionsfor fans or pumps after disconnectionof the control voltageYour advantages Flexible use for all contactor control supply voltagesin the 24 – 240 V AC/DC range Selectable outputs 1 NO 1 NC or 1 CO All modules with 24 – 240 V AC/DC wide voltage in the auxiliary circuit Integrated electric interlocking and factory-integrated varistor(protective circuit) - easy configuration Plug-on function modules for connection without tools High setting accuracy thanks to selectable time ranges Reduced variance – only 1 module for sizes S00 and S0 Add-on modules for reduced wiring and space savingsDifferences SIRIUS 3RA2811 / 12 / 16 and 3RA2813 / 14 / 15 Unlike DIN rail mounted timing relays, 3RA2811 / 12 / 16 functionmodules do not feature any relay outputs. They represent timingrelays which are directly mounted on 3RT2 contactors. Instead of thecontactors, the function modules are controlled which then switchthe contactors below via direct contact with the contactor coil. With 3RA2813/14/15 time-delayed auxiliary switches, the 3RT2contactor is controlled which then switches on or off instantaneously.The auxiliary switch mounted on the contactor responds to this viavoltage tap on the contactor coil and switches the relay outputs witha time delay.93RA2813 / 14 / 15 Time-Delayed Auxiliary Switches3RA2813 / 14 / 15 Time-Delayed Auxiliary Switches

3UG458 Monitoring Relaysfor insulation monitoringApplicationAmongst others, IT networks areemployed in the following applications: Emergency power supply systems Emergency lighting systems Industrial production plants withhigh availability requirements(chemical industry, automotiveindustry, printing industry) Marine and railway applications Mobile current generators (airplanes) Renewable energies, e.g. wind energyand photovoltaic plants Mining3UG458 Monitoring RelaysInsulation monitoring relays are used for monitoring the insulation resistance between ungrounded single orthree-phase current supplies and a protective conductor. Ungrounded, i.e. isolated networks (IT networks) arealways used where high demands are placed on the reliability of the power supply, e.g. emergency lighting systems. After an initial insulation fault it is possible to continue working in safety (single-fault safety). The faultmust still be rectified as quickly as possible before a second insulation fault occurs (e.g. according to DIN VDE0100-410). For this purpose insulation monitoring relays are used which constantly measure the resistance toground of the phase conductor and the neutral conductor, reporting a fault immediately if insulation resistancefalls below the set value.Your advantages Devices for AC and DC systems All devices with wide supply voltagerange Direct connection to networks with linevoltages up to 690 V AC and 1000 V DCvia voltage reducer module With AC networks: Frequency range15 . 400 Hz Monitoring for line breakage Monitoring for faulty settings Application safety thanks to integratedsystem start after start-up Reset and test option (via button onthe front or control contact) Rapid response times thanks to newpredictive measuring principle15

3RN1 Thermistor Motor Protectionfor protection against overheatingThermistor motor protection relays provide decisive benefits in cases in which current-dependent protection using either a circuit breaker or an overload relay is not the perfect solution: In specific cases, often as a result ofexternal effects, overheating can occur without being detected by the thermal image in the circuit breakeror overload relay. Examples for this include heavy-duty starting (e.g. centrifuges), operation with frequency converters or frequent switching, braking operations or when cooling is restricted, e.g. due to accumulated dirt.Application3RN1 Thermistor Motor Protection Protection of motors against overheating, particularly with heavy-dutystarting, braking operation, frequentswitching or insufficient cooling “Warning and disconnection” functionbased on two sensor circuits withdifferent response temperatures forresponding prior to disconnection(additional cooling, load reduction, etc.) Multiple motor protection with onlyone device, e.g. with conveyor linescomprising multiple motors which areto be disconnected jointlyYour advantages Direct measuring of the motor windingtemperatureCharacteristics for type A thermistor sensor Device/terminal labeling acc. to DIN EN50005 for “normal” switching relays andfor overload protection systems4000R Relays with hard gold-plated contactsfor application under difficult conditions1330550 Indication of wire breakage and shortcircuit in the sensor circuit via LED25020–20 C 018 Only one device for all motor powerratingsTNF-20 TNF TNF 15 TTNF-5 TNF 5 Version with safe isolation up to 300V in accordance with DIN/VDE 0106 aswell as version with bistable relays forspecial cases ATEX approval for gases and dust
