Siemens SENTRON 3WL10 - Power Supply, Grounding, and Connection

• Simple integration into plant monitoring systems for monitoring
– Status
– Measured values
– Alarms and warnings
– Diagnostics
– Maintenance
• Signi󹪝cant additional bene󹪝ts for the switchboard due to the possibility of connecting
external input and output modules to the 3WL10 air circuit breaker
• Innovative software products for commissioning, testing, parameterization, operation,
monitoring, documentation, and diagnostics of circuit breakers on site at the display, via the
front interface using test devices or communications modules
• Integration of the circuit breakers into the Totally Integrated Power (TIP) and Totally
Integrated Automation (TIA) solutions
Direct connection via two communications modules
Connection to the communication environment is established directly via modular, pluggable
communications modules in conjunction with the Breaker Connect module on the auxiliary
conductor terminal system.

① Fixed-mounted breaker
② Withdrawable breaker
Because the circuit breaker is designed for up to two communications modules, it can be
integrated into the communication environment with two di󹪜erent protocols. For example,
simultaneous connection of a 󹪝eldbus for automation or remote control applications (incl.
parameterization and remote switching) and Modbus TCP Ethernet communication link for
communicating measured values for e󹪟cient and safe power monitoring.
