SIEMENS SIPROTEC 7VK87 BREAKER MANAGEMENT DEVICE

Product Description

SIEMENS SIPROTEC 7VK87 breaker management device

The breaker management device SIPROTEC 7VK87 is part of thenew SIPROTEC 5 series of modular, flexible and intelligent digital fielddevices. With its modularity and flexibility and its high-performance DIGSI 5engineering tool, the SIPROTEC 7VK87 fits perfectly for protection, control,monitoring, and measuring applications in electrical energy systems. Mainfunction: Automatic reclosing, synchro check, circuit-breaker failureprotectionTripping-1- and 3-pole or 3-poleInputs and outputs:-12 predefinedstandard variants with 4/4 or 8/8 current/voltage transformers,-5 to 31 binaryinputs,-4 voltage transformers-8 to 46 binary outputs Hardware flexibility: Flexiblyadjustable I/O quantity structure within the scope of the SIPROTEC 5 modularsystem Width of housing:1/3 x 19'' to 2/1 x 19''

Alll functions can be configured freely with DIGSI 5. Forthe application of some of the functions, you require the appropriate number offree function points within the device. The function point calculator in theonline configurator provides support in determining the required number offunction points for your device.
