What this SENTRON COM compact MCB packs in one module width
What sets it apart from a standard MCB is the built-in metering suite: an ammeter, voltmeter, wattmeter, frequency meter, and reactive power meter are all integrated into the same 18 mm-wide housing. That means you get branch-circuit protection and energy monitoring in a single 1-module-width unit — no separate panel meter or current transformer needed for basic per-circuit power tracking. Accuracy on the current and voltage measurements is 0.5 % per IEC61557-12, IEC62053-22, and IEC62053-23, which is solid for submetering in residential or light commercial infrastructure.
Tested to IEC/EN 60898-1 and GB/T 10963.1. Energy limitation class 3. Neutral conductor switched with phase. Wireless protocol support listed for remote metering communication.
