It is rated 25 A at AC with a 30 mA residual fault current trip, Type A (pulsating DC and AC sensitive), tripping characteristic C. The unit occupies one modular width on a DIN rail, saving panel space compared to separate MCB + RCCD combinations. Rated breaking capacity is 4.5 kA per EN 60898 and 5 kA per IEC 60947-2, with overvoltage category III and pollution degree 2 — suitable for final circuits in residential and commercial distribution boards.
The 25 A rating at 30 °C derates to 23.75 A at 40 °C, 23 A at 45 °C, 22.25 A at 50 °C, and 21.5 A at 55 °C. If your panel ambient runs above 30 °C, size the load accordingly — a 25 A circuit at 50 °C can only carry 22.25 A continuously without nuisance tripping. The 30 mA residual current trip, Type A, covers sinusoidal AC faults and pulsating DC faults up to 6 mA smooth DC — the standard for general socket-outlet circuits and most single-phase equipment. The instantaneous design (no intentional delay) trips within 40 ms at rated fault current, which meets the disconnection times in IEC 60364 for TN and TT systems. For high-inrush loads (large transformers, motor starters), characteristic D would be a better fit.
Snap-on DIN rail mount, 1 MW (18 mm wide), 77 mm depth, 90 mm height. Installation depth is 70 mm — verify your enclosure depth clears this. Touch protection is provided on the terminals. Mount in a clean, dry enclosure.
