Whether for industrial plants, data centres or airports, failsafe power distribution must fulfill increasingly stricter requirements. The intelligent interlinked SENTRON components reliably help protect people, cables and plants against the danger of electric shock. You get everything as a one-stop safety solution: a perfectly coordinated portfolio and state-of-the-art products, rounded out by planning tools and engineering data.

Integrated Communication
Communication-capable components enable integration in automated digital environments, make energy flows transparent, and ensure completely safe power distribution.

Fail-safe power supply
Our components ensure a fail-safe power supply and can be integrated seamlessly into holistic energy efficiency concepts and into building and industrial automation.

Professional software and data enable efficient, standard-compliant planning and error-free configuration and documentation.

Buildings, infrastructures, and industries 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. Siemens SENTRON protection devices 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. This is why they are the best at providing a technical basis for a safe, efficient power supply.

3WL Air Circuit Breakers
Every power supply depends upon a reliable infeed of electricity. 3WL air circuit breakers reliably protect electrical installations against damage or fire as a result of short circuits, ground faults, or overload faults.

Molded Case Circuit Breakers
The 3VA molded case circuit breakers set new standards in flexibility and the variety of modular accessories available. Standardized accessories suitable for use with several sizes of the 3VA molded case circuit breaker up to 1000 A together with quick and easy installation help to cut costs and save time.

Residual Current Protection Devices (RCBOs)
The compact 5SV1 RCBOs reliably protect different electrical circuits against fault currents. They combine residual current detection and overcurrent protection in just one modular width (MW) and ensure reliable personal and cable protection in numerous areas of application with just one device.

Miniature Circuit Breakers
The Siemens portfolio of SENTRON MCBs, are easy to assemble and install, feature a uniform design, and can be expanded to include many more functions thanks to an extensive range of accessories. Meeting the evolving requirements of automated buildings and industrial power supply systems and applications, the extensive portfolio has the right MCB for every application.

With the SENTRON portfolio, APS provides a comprehensive product offering that meets all requirements and is flexible enough for any application. Extensive and modular accessories enable simple function expansions. The long service life and low maintenance requirements of all components offer you long-term reliability.
