It's a 2-pole (1P+N) design with a C-curve tripping characteristic, rated for 230 V AC and a full-scale current of 33 A. The integrated metering suite — ammeter, voltmeter, wattmeter, frequency meter, and reactive power meter — gives you live power-quality data without adding a separate panel meter. The AFDD function detects series and parallel arc faults per IEC 62606, so this unit covers both overcurrent protection and arc-fault protection in a single DIN-rail module.
The 33 A full-scale is the maximum continuous current the metering electronics are calibrated for; the MCB's thermal trip element is sized for the same 33 A nominal. If your load draws more than 33 A steady-state, step up to the next frame size. The 6 kA rated short-circuit capacity (IEC 60947-2) is adequate for most sub-distribution boards fed from a transformer with typical impedance. Environmental range is wide: -40 °C to +75 °C operating/storage, pollution degree 2, overvoltage category III.
Depth is 68.5 mm, installation depth 70 mm — verify enclosure depth clearance, especially in shallow pull-boxes. Front face is IP40; rear side is IP20. With conductors and protective device connected, the overall assembly meets IP20.
