3Na Com Fuse - Siemens Sentron 7KN POWERCENTER 1000 Manual

The measured values and states are wirelessly transmitted via the integrated communication
and metering function. Thus, the final circuit can be monitored even further, by e.g. setting a
limit value that sends a warning when a certain current or voltage value is exceeded. This
predictive error detection ensures increased system availability. In addition to the electrical
measured values (current, voltage, frequency, power, energy) of the circuit, values such as
tripping type, temperature, switching cycles or operating cycles are also communicated.
Even here, the 1+N pole design of the switch offers the complete scope of protection,
without additional connections for the communication function. As a result of the compact
size of 1 TE, the 5SV6 COM arc fault detection devices offer a simple exchange of
conventional arc fault detection devices or miniature circuit breakers. Devices with a compact
structure (1+N) can be easily exchanged, for the single-pole devices the neutral conductor
must also be connected. The 5SV6 COM is available for nominal currents of 6 A to 32 A and in
tripping characteristics B and C.

3NA COM fuse

The 3NA COM fuses with communication and metering function not only protect the circuit,
but also enable early error detection by measuring the current and temperature.
Monitoring of the circuit makes it possible to combat the cause even before the fuse trips by
being able to generate warning messages when the set over-current limit or even the
temperature limit has been exceeded. This contributes towards the avoidance of power
outages, or a reduction of power failures and thus, increases the availability.
