●
Retrofittable functions for electronic trip units
Upgrading the electronic trip units is possible at any time. This is done simply by
replacing the ETU. For example, the RC functionality can be added by replacing the
rating plug in the ETU660.
Rating plugs, the metering function, and communication modules for the electronic trip
units are available for fast and easy retrofitting and adaptation to changing requirements.
Subsequent upgrading of the ETUs of the 3-series to the ETUs of the 6-series is possible.
●
Flexible communication / metering function
The use of modern communication-capable circuit breakers opens up completely new
possibilities in terms of start-up, parameterization, diagnostics, maintenance and
operation. This allows many different ways of reducing costs and improving productivity in
industrial plants, buildings and infrastructure projects to be achieved:
–
Simultaneous use of up to two different bus systems, such as PROFIBUS,
PROFINET, Modbus TCP, or Modbus RTU
–
Fast and reliable parameterization
–
Timely information and response can prevent plant stoppages
–
Effective diagnostics management
–
Measured values are the basis for efficient load management, for drawing up power
demand profiles, and for allocating energy to cost centers
–
Preventive maintenance reduces the risk of expensive plant downtimes
–
Metering function with a very wide range of measured values, such as current,
voltage, energy, power
Applications
●
As incoming feeder, distribution, coupling and outgoing feeder circuit breakers in
electrical installations
●
For switching and protecting motors, capacitors, generators, transformers, busbars, and
cables.
●
When connected to an electronic I&C system, the 3WL10 air circuit breakers offer a wide
range of options for monitoring network events.
