Breaking capacity — the ratings that matter for fit
This breaker carries multiple breaking capacity ratings depending on the standard applied: 6 kA per EN 60898, 10 kA per IEC 60947-2 at 400 V AC, and 15 kA per IEC 60947-2 at DC (72 V max). For UL 1077 / CSA C22.2 No. 235 applications, it's rated 5 kA at AC. The energy limiting class is 3, meaning it restricts let-through energy well enough to protect downstream components in a properly coordinated system.
Installation and environmental notes
Ambient temperature range is -40 °C to 75 °C, with derating for humidity: max 95% RH up to 55 °C, tapering to 35% RH at 75 °C. Touch protection is built in per the product feature listing.
