Rated 25 A with a B-curve magnetic trip characteristic (3...5 x In), it provides 6 kA Icn breaking capacity per IEC 61009-2-1 and 10 kA Icu per EN/IEC 60947-2.
The 6 kA Icn is the service breaking capacity for routine faults; the 10 kA Icu rating (per EN/IEC 60947-2) gives the ultimate short-circuit withstand for coordination studies. In a panel, the 36 mm width and clip-on DIN rail mount mean it replaces a standard 1P+N MCB/RCD slot without re-spacing. Measurement accuracy is specified at ±2 % for voltage and current, ±5 % for active power — figures that support energy monitoring but not revenue-grade metering. The thermal-magnetic trip unit provides the overcurrent protection; the arc-fault detection circuit monitors the waveform for series and parallel arc signatures per EN/IEC 62606.
Deployment context
Clip-on DIN rail mounting and IP20 finger-safe terminals (tunnel type, accepting 1...16 mm² rigid or 1...10 mm² flexible) make this a panel-board component. The 73 mm depth fits standard 100 mm deep enclosures. Cable entry from top and bottom, with a 14 mm wire stripping length and 2 N·m tightening torque, matches usual panel-building practice. Tropicalisation severity B per IEC 60068-2-30 (28 days) confirms suitability for humid environments.
