TIASTAR Motor Control CenterESP100 Solid State OverloadsESP100 solid state overload relays areself powered, requiring no separate120V source to power the circuit board.They provide phase loss protection,fewer connection points and high repeattrip accuracy which results in longermotor life and cost savings. NEMAClass 10, 20 and 30 trip curves areavailable for a variety of applications.The ESP100 solid state overloadprovides phase loss protection for themotor by tripping within three secondsupon complete loss of one phase of athree phase motor branch circuit.Each overload has at least a 2:1 currentadjustment range with the adjustmentdial reading out in full load amps. Inaddition to the markings on the dialthere are audible clicks which allowfor extremely fine tuning.The heaterless construction of theseoverloads minimizes energy costs andthe costs of cabinet ventilation orcooling. Solid state overloads can beused at temperatures from –30°C to70°C and are rated for 50Hz and 60Hzapplications.ESP100 panel mounted overloads can beused to upgrade existing starterapplications where panel mountedthermal overloads are used. In addition,ESP100 overloads can be panel mountedwhen used with other types ofcontrollers, such as DP, IEC contactors,and soft starts.ESP100 overloads can be used on highvoltage applications, making them idealfor use with vacuum contactors andother high voltage control.ESP100 overloads can be retrofittedon existing contactors using the retrofitplate suffixes or on other brands usingthe plates listed in the competitiveretrofit plates table on page 16-48.SIMOCODE ProSIMOCODE Pro is the latest generationof Motor Management System(“Smart Overload”) bringing a new levelof flexibility and functionality within theSiemens smart motor control center.By means of a PROFIBUS DP interface,it can easily be linked to higher-levelautomation systems. SIMOCODE Proimplements all motor protection andcontrol functions, determines operational,diagnostic and statistical data andorganizes the communication betweenthe automation system and MCC bucket.The SIMOCODE Pro consists of twodevice series with different levels offunctionality:SIMOCODE Pro C (Compact)The compact motor management systemcan be used for Full Voltage Nonreversing(FVNR) starters, Full VoltageReversing (FVR) starters, and baseoverload functionality.CT ModuleSIMOCODE Pro V (Variable)The variable motor management systemhas an even greater range of functions,including voltage and power monitoringand expandable modules for additionalI/O, as well as temperature and groundfault protection.CT ModuleKeypad(Door Mounted)SIMOCODE Pro CSIMOCODE Pro VProduct OverviewThermal OverloadsBimetal Ambient CompensatedBimetal ambient compensated overloadrelays protect both the motor andequipment by opening the control circuitwhen the motor experiences an overloadcondition. The bimetal overload relay maybe set for either manual or automaticreset and can be supplied with standardClass 20 heater elements or optionalClass 10 heater elements as required.An ambient compensated model of thebimetal overload is available.Bimetal Ambient Compensated Overload15MOTOR CONTROLCENTERSExpandable ModuleKeypad(Door Mounted)Note: For detailed information on the SIMODE Pro pleasecontact the local Siemens Sales Office.ESP100 Solid State OverloadSiemens Power Distribution & Control, SPEEDFAX 2007-2008 Product Catalog 15-3
