Circuit breakers with communication and measuring function
The circuit breakers with communication and measurement functions are an essential component of SENTRON digitization solutions.
System availability is increased by reacting to alerts early. The protection functions still offer safe, reliable protection in the final circuit. The communication and measurement functions in turn make it easier to find the causes of malfunctions due to the reporting of the cause of the trigger, while WAS in turn allows conclusions to be drawn about malfunctions of operating devices. A further advantage is the integrated operating hours and activation counters, which contribute to better predictability of maintenance. In addition, the protective switching devices record electrical parameters such as energy, effective power, current, voltage, mains frequency and temperature with measurement and communication function. Thus the transparency is increased and the energy consumption in the final circuits can be broken down. Setting alarm thresholds and measuring differential currents in multiple frequency ranges enables accurate locating of the causes of faults.
Because of their compact design, the Ideal protection relays are suitable for retrofitting or for the new building. The system can be easily commissioned using the SENTRON Powerconfig or SENTRON Powerconfig mobile PC software for mobile devices.

The SENTRON PowerCenter 1000 data transceiver is at the heart of the system of protective switchgear with communication capability. This collects measured values of the coupled protection switching devices and transfers them to higher-level systems. The measured values from up to 24 SENTRON devices with communication capability are transmitted wirelessly to a SENTRON 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. On-site, either via Bluetooth® or via Ethernet in the local network. A Modbus TCP protocol is used, which can be easily integrated by other systems.

5ST3 COM RCA standard and 5ST3 COM RCA RCD-test
5ST3 COM remote drives not only provide the capability to monitor the system or the attached main devices, but also the ability to switch remotely. These devices are supported in PowerCenter 1000 and later firmware version 3.0.

The standard measuring functions of the device temperature, operating hours and number of shutdowns are supplemented by other functions, such as the exact breakdown of the switch position, whether manually, automatically or remotely switched or the switching command, an automatic restart function (ARD) after triggering and its parameterization.

In addition, the RCD test variant of the remote drive (5S3073‑0MC) enables the execution of individual or recurring FI (RCD) or Insulation resistance (IR) tests according to IEC 63024, depending on the implement configured. The time and test results are recorded in a memory and can be exported afterwards.

With the standard version (5S3072‑0MC), wired connections for an auxiliary and error signal contact are available instead of the test function.

Both versions are supplied with a 100-240 V AC supply voltage.
