Why SENTRON COM?

SENTRON measuring and communication-capable circuit protection devices offer high-level transparency needed to prevent outages, ensure availability and minimize operating costs. Their ability to integrate into digital solutions allows for advanced energy and maintenance management. They protect and monitor electric circuits, or bundle and forward the measured values.

Our portfolio includes devices that collect and store data, protect against overloads and fires, safeguard electronic circuits, and enhance system monitoring and transparency.

Key benefits

Protect people and plants proactively

Set individual threshold values to receive early warnings before faults occur. Precise fault localization minimizes downtime, ensures stable power supply, and keeps your plant running at peak availability.

Predict failures and respond faster

Identify risks before they cause failures – monitor components, plan maintenance during scheduled downtime, and respond quickly to faults. This reduces unplanned outages and keeps operations running smoothly.

Cut energy costs and simplify installation

Analyze consumption down to the final circuit to optimize energy costs and enable load shifting. The compact single-width design reduces wiring effort and speeds up installation for quick, error-free commissioning.
