Circuit Protection Devices With Communication And Metering Function - Siemens Sentron 7KN POWERCENTER 1000 Manual

Circuit protection devices with communication
and metering function
Circuit protection devices with communication and metering functions are an integral part of
SENTRON digitalization solutions.
System availability is increased by the early response to warning messages. The protection
functions still offer secure, reliable protection in the final circuit. As a result, the
communication and metering function makes it easier to find the causes during malfunctions
due to reporting the cause of the tripping operation, which in turn allows conclusions to be
drawn about malfunctions of operating equipment. Another advantage is provided by the
integrated operating hour and trip counters, which contribute to improved planning of
maintenance work. In addition, circuit protection devices with a metering and
communication function capture electrical parameters such as energy, active power, current,
voltage, line frequency and temperature. This helps increase transparency and energy
consumption in the final circuits can be broken down.
Due to their compact construction, the circuit protection devices are ideal for the retrofit
market or even new construction. The system can be simply put into operation via the
SENTRON powerconfig PC software or the corresponding SENTRON powerconfig app for
mobile devices.

The 7KN Powercenter 1000 data transceiver is the core of the system of communication-
capable circuit protection devices. This gathers measured values of the coupled circuit
protection devices and transfers them to the higher level systems. The measured values from
up to 24 communication-capable SENTRON devices are wirelessly transferred to a
7KN Powercenter 1000, which stores selected data for up to 30 days. Higher-level systems
can access the data via the interfaces of the data transceiver. Either on site via Bluetooth or
via Ethernet in the local network. In this case, a Modbus TCP protocol is used, which can
easily be integrated by other systems.
