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.
