Its C-curve tripping characteristic means it tolerates moderate inrush — typical for motor starters, contactor coils, and small transformers — without nuisance trips, while still clearing faults fast. Rated 15 kA per EN 60898-1 and 40 kA per IEC 60947-2, it covers most panel fault-current levels up to 400 V AC. The 36 mm width occupies two modular units on a DIN rail, matching standard panel layout grids.
Two breaking-capacity ratings let you size the part to the applicable standard. Under EN 60898-1 (household and similar installations) it's rated 15 kA; under IEC 60947-2 (industrial) it's rated 40 kA. For UL 1077 / CSA C22.2 No.235 supplemental protection, it carries 5 kA. The 40 kA industrial rating gives headroom for high-fault panels — useful when coordinating with an upstream 63 A or 100 A molded-case breaker without cascading. The C-curve magnetic trip (5–10× In) pairs well with motor branch circuits where the starting surge is short but significant.
Any mounting position. Depth 76 mm, height 90 mm, width 36 mm — two modular units. Pollution degree 3 handles conductive dust environments typical of industrial control rooms.
Compliant with IEC / EN 60898-1, IEC / EN 60947-2, and UL 1077. Halogen-free and silicon-free construction. Overvoltage category III — suitable for fixed-installation distribution boards. Energy limitation class 3 — limits let-through energy in a fault. Sealable for lockout/tagout procedures.
