The DC rating of 15 kA at 60 V (72 V max) extends its use into DC auxiliary circuits, control power supplies, and battery-backed loads — a single part number for mixed AC/DC panels. The quick-assembly fastening method and any-position mounting simplify panel layout — no orientation constraints when you're packing breakers into a tight gland plate.
Rated under IEC / EN 60898-1 for domestic-style installation and IEC / EN 60947-2 for industrial application, plus UL 1077 recognition for North American supplementary protection. The pollution degree 3 rating and overvoltage category III mean it's designed for fixed installations inside a panel, not for handheld or outdoor use.
Integration notes
Combined terminal at both top and bottom accepts supply from any direction — no need to flip the breaker for top-feed vs bottom-feed panels. Neutral conductor is not switched (2-pole without switched neutral), so this breaker protects two phase conductors only; a separate neutral bar is required downstream. Ambient derating applies above 55 °C: max 95% humidity at 55 °C, dropping to 55% at 70 °C and 35% at 75 °C. If the breaker sits near a heat source (transformer, drive heatsink), factor that into the load calculation — the thermal-magnetic trip element responds to both current and ambient temperature.
