Protecting electrical installations from damage The number of electrical loads is constantly increasing, which places an ever greater load on the electrical installation. In the event of an overload or short-circuit, miniature circuit breakers safely cut off the connected circuit and reliably protect electrical installations and equipment from damage. Miniature circuit breakers from the SENTRON portfolio are also simple to mount and install. The devices have a uniform design and, with the appropriate accessories, can be expanded by many additional functions. For industry, buildings or infrastructure – with our versatile portfolio, you will find a suitable miniature circuit breaker for any application. Communication and measuring capable miniature circuit breakers In addition to the protective functions of the standard devices, the communication and measuring capable MCBs bring transparency to the final circuit and can react even before the fault occurs. The system availability is increased. Information on the switching status enables predictive maintenance.The standard 5SY MCBs, 5SP4 MCBs and 5SL MCBs can be easily expanded with the communication and measuring capable auxiliary witch / fault signal contact.
