Overview - applications and portfolio
This chapter provides an overview of the circuit breakers and describes the potential areas
of application for different circuit breaker models.
The topics discussed in this chapter are listed below:
● Applications and possible uses
● Portfolio
● Possible configurations
● Detailed information about applications and possible uses
● Technical specifications
● Molded case circuit breakers and accessories in the system
Basic properties of the circuit breaker (3WL10 / 3VA27)
● Choice between two ranges of electronic trip units with a number of equipment versions:
– Electronic trip units (ETUs) of the 3-series with rotary coding switches
– Electronic trip units (ETUs) of the 6-series with LC display for additional settings and
functions for enhanced requirements (communication and metering function)
● Variable and versatile connections with identical dimensions (3WL10 / 3VA27)
● Options for integration into switchboards complying with IEC 61439-2
● Optional expansion with a wide range of internal and external accessories
● Integrated communication concept together with the other 3VA molded case circuit
breakers, the 3WL, and the 7KM PAC measuring devices. Option of direct integration into
the Siemens communication environment via optional accessories (with ETUs of the 6-
series):
– Communication modules (Plug & Play) for PROFIBUS DP, PROFINET IO,
Modbus TCP, and Modbus RTU
– I/O modules
– Modules with expanded metering functions for efficient energy management
● Integration of the circuit breaker into the Totally Integrated Power (TIP) solutions is
possible
● Integration into the SENTRON software environment, including powerconfig and
powermanager
Support by CAx files and Siemens tools simplifies planning and integration of the circuit
breaker into the overall installation.
