It's built to IEC 60947-2 for distribution duty — the standard that covers air circuit breakers for industrial power systems. The drawout mounting means the breaker slides out of its cradle for safe maintenance without disturbing the busbars, a real time-saver when you're swapping a unit on a live panel. Breaking capacity is 50 kA Icu at 220...440 V AC and 42 kA at 690 V AC, with matching Ics (service breaking capacity) at the same levels — meaning it can clear a fault and be reclosed without repair. Rated insulation voltage is 1000 V AC, so it's comfortable on 690 V systems with headroom. Impulse withstand is 12 kV, which covers most industrial surge environments.
If your panel runs hotter than 40 °C, you'll need to derate per the manufacturer's curve. Electrical durability is 6,000 cycles at 440 V and 4,000 at 690 V without maintenance, which aligns with Category B utilization per IEC 60947-2. The 25 ms maximum breaking time is fast enough to coordinate with downstream breakers in a selective scheme.
