Circuit Breakers

Buildings and infrastructure are increasingly automated, and there are new technologies and stricter standards. These developments require intelligent solutions for power distribution and electrical installations. It is important to ensure high system availability and optimise energy consumption while protecting people and plants. The Siemens range of SENTRON circuit breakers are rigorously designed to meet these requirements, and they offer both protection functions and ways to integrate the devices into automation environments and collect energy data.

Air Circuit Breakers (ACBS)

Siemens 3WL air circuit breakers from APS Industrial reliably protect electrical installations against damage or fire as a result of short circuits, ground faults, or overload faults.
