Breaking capacity hits 30 kA at 400 V, 100 kA at 240 V, and still holds 2 kA at 690 V — enough to clear a fault upstream of most downstream contactors without cascading.
The 32 A rating at 480 V and 32 A at 600 V means this breaker directly protects a motor drawing up to 32 A full-load — typical for a 15 kW (20 hp) 400 V motor or a 10 hp 480 V motor, depending on service factor. CLASS 20 trip allows up to 20 seconds at 600% of rated current before opening — enough for high-inertia loads like fans or compressors, but not for extremely long-start loads that would need CLASS 30. Terminals accept 2x (0.5... 1.5 mm²) or 2x (0.75... 2.5 mm²) solid or stranded, with M6 main contact bolts — standard for panel wiring up to 32 A.
