It's rated for 70 kA breaking capacity at 230 V AC per IEC 60947-2, and 15 kA at DC up to 72 V — numbers that tell you it'll handle high-fault industrial panels without cascading upstream. The C curve means it's meant for motor and transformer inrush, not pure resistive loads; you'd use it on a conveyor drive or a compressor branch, not a lighting circuit. IP20 with conductors connected — fine inside a closed enclosure, not for washdown zones.
Installation depth is 70 mm plus the breaker body depth of 76 mm — factor that into enclosure back-panel clearance. The combined terminal at top and bottom accepts copper conductors; neutral is switched internally, so no external neutral bar needed for the protected circuit. Sealable with a lead seal if the panel requires tamper evidence. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. That's enough for pump skids and conveyor frames, not for direct engine mounting.
