The 2-pole (1P+N) configuration switches the phase and provides overcurrent protection on the phase only, with the neutral switched but not protected; this is common in single-phase sub-distribution boards where a shared neutral bus is not desired. Breaking capacity is 15 kA at 230 V AC per EN 60898, and 25 kA per IEC 60947-2 — the higher figure applies when the breaker is used in industrial distribution where the prospective short-circuit current is higher. The 15 kA DC rating per IEC 60947-2 at 72 V covers DC auxiliary circuits. Rated for 50/60 Hz networks, with an ambient temperature range of -40 to +75 °C (operating) and -40 to +70 °C (storage).
Terminal capacity and installation
Installation depth is 70 mm, and the overall depth including the front toggle is 76 mm. Halogen-free and silicon-free construction matters in environments where outgassing from a fault could damage sensitive electronics or contaminate clean-room processes — common in semiconductor fabs, medical device assembly, and food processing lines. The energy limiting class 3 indicates the breaker limits let-through energy during a short circuit, reducing stress on downstream wiring and equipment.
