Its C-curve tripping characteristic handles moderate inrush loads — motors, transformers, capacitor banks — without nuisance trips, while still clearing faults fast. Rated 400 V AC (multi-phase up to 440 V) and 60 V DC (max 72 V DC), it covers the common panel voltages. UL 1077 recognition (5 kA) also holds for North American installations, so it's a single SKU that spans both IEC and UL jurisdictions.
Mounting position any, so vertical or horizontal busbars are fine. Rated for pollution degree 3 (conductive or dry non-conductive pollution) and overvoltage category III, which is standard for fixed-installation distribution. IP20 with connected conductors — fine inside a sealed enclosure.
