At 440 V AC the same breaker still clears 25 kA Icu, which covers most industrial motor-control center bus faults. The thermal-magnetic element handles overloads (thermal) and short-circuits (magnetic) in one package — no separate relay needed for most distribution boards.
Fixed backplate mount, front connections both top and bottom. IP20 finger-safe terminals, IK07 impact resistance — it's a panel interior part, not a washdown enclosure breaker. Dimensions are 165 mm high, 140 mm wide, 68 mm deep — fits standard distribution cubicle cutouts. The toggle handle gives positive contact indication so you can visually confirm the contact position without removing covers.
Built to EN/IEC 60947-1 and 60947-2, plus JIS C8201-2-2 and GB/T 14048.2. That covers the main global markets — IEC for Europe/Asia, GB for China, JIS for Japan. Rated operational voltage 440 V AC, insulation voltage 440 V AC. Mechanical durability 10,000 cycles — enough for distribution switching, not for daily motor-starting duty.
