Low-voltage power distribution
3WL/3VL circuit breakers
Modular circuit breaker with built-in communication
interface to your automation system
Circuit breakers are now more than just high-quality switching and protective
devices. Via standardized bus systems, the 3WL communicationcapable
air circuit breakers and 3VL molded-case circuit breakers send
measured values, switch status information, important diagnostic, fault,
maintenance or cost center management information to a central
control room or an automation system.
The circuit breakers of the SENTRON family fit seamlessly into the automation
architecture and increase the availability of your plant. Plus, you
can optimize the energy distribution process with a networked power
management solution. Never before have circuit breakers been so versatile
and so simple to use.
Communication-enabled circuit breakers
The 3VL molded-case circuit breakers fulfill your requirements with
regard to space requirements, plant availability and security:
• Integrated communication via PROFIBUS DP and Modbus RTU
• Wide range of measured values
• Extensive diagnostics, maintenance and servicing functions
• Increased plant availability
