Siemens AG 2010SENTRON 3VLMolded Case Circuit BreakersSwitching, Protection, Measuring and Monitoring DevicesFor the operating range from 16 A to 1600 A, the molded case circuit breaker ensuresthe optimum overload and short-circuit protection. For new plants, the SENTRON 3VLmolded case circuit breakers with integrated communication are the best solution.Recording of the measured values is an integrated component of the switch.Compact and communication-capableCompact dimensions and optimum communication capability are the main featuresof the SENTRON 3VL molded case circuitbreaker. The space-saving circuit breakeris used for plant and motor protection, forstarter combinations or as a non-automaticair circuit breaker, as required.7Flexible and comprehensiveThe molded case circuit breaker is availableboth with thermal-magnetic overcurrentrelease (16 A to 630 A) and with electronicovercurrent release (63 A to 1600 A), andtherefore supplies a wide-ranging productspectrum in all application areas. Two internal series of accessories complete the product portfolio.Highlights7Universal communication solutions,also in combination with theSENTRON 3WL air circuit breaker7Thermal-magnetic or solid-statetripping units ensure a wide-rangingproduct spectrum in all applicationareas7Flexibility and variable possibilitiesfor use with extensive accessories7Answers for infrastructure.

Siemens AG 2010Unlimited communication:with the innovative COM20 and COM21 modulesFor the economic and safe operation of the plant, transparency in energy distribution is the basic requirement – and thisis satisfied completely with the COM20/21. By integrating themodules, all ETU versions can communicate universally viaPROFIBUS/MODBUS.Whether switch status, trigger cause, alarms, current measurement, event log, switching cycles or device controls: The costsand function-optimized COM20/21 reliably transmit all importantinformation so that there is transparency regarding the status ofyour plant at all times.Further benefits of the COM20/21 solution Can be used universally – even with the cheap ETU,universal communication is possible Easy installation through optimized ETU connection Maximum flexibility thanks to smaller size for spaceoptimization in the control cabinet Particularly uncomplicated, as no auxiliary and andalarm switch wiring to the communication module3VL circuit breaker and communication US8115710111SENTRON 3VL11 Measurement function Plus2Electronic ETU release12 ZSI module3COM20 PROFIBUS module1) complete with ZSI13 Digital output module with relay contacts4Breaker Data Adapter (BDA)14 Digital output module with relay contacts, configurable5BDA Plus with Ethernet interface15 Analog output module6Browser-capable input and output device (e.g. notebook)16 Digital input module7SENTRON 3WL17 Switch ES Power on PC8COM15 PROFIBUS module2)18 PLC e.g. SIMATIC S79Breaker Status Sensor (BSS)10 Electronic ETU release1)2)For a MODBUS connection the COM21 module is required.For a MODBUS connection the COM16 module is required.Increased plant availability through multi-family communication4I202 022922Circuit Breakers19 SIMATIC powerrate20 SENTRON PAC5
