The 'H' breaking capacity code means it delivers 100 kA Icu at 220/240 V AC and 70 kA at 380/415 V AC — headroom that keeps fault energy contained within the device rather than cascading upstream. That matters for a distribution board where the transformer or bus rating is set at 65 kA; this breaker clears faults well above that level without coordination loss. Rated 63 A at 50 °C. Power dissipation is 8.61 W per pole. IP40 enclosure protection keeps out tools and fingers; IK07 impact rating handles incidental knocks during panel assembly.
Integration notes for the panel builder
The 35 mm connection pitch matches standard busbar systems and cable lug spacing. Five accessory slots on the front accept auxiliary contacts, shunt trips, or alarm switches without increasing the breaker footprint. Mounts flat on the backplate in either horizontal or vertical orientation. Front terminals on both line and load sides simplify busbar routing and cable dressing in a multi-breaker lineup. Toggle handle provides manual ON/OFF with clear visual indication. Electrical durability: 50,000 cycles at 440 V at rated current, 30,000 cycles at 440 V at In. Mechanical durability matches at 50,000 cycles. Suitable for isolation per EN/IEC 60947-2 — a lockable handle option (not included) would be needed for lockout/tagout compliance.
