It's a distribution-grade breaker (Category A per IEC 60947-2) for fixed backplate mounting in panels. The 10 kA Icu at 550 V AC and 100 kA Icu at 110–130 V AC tell you where it can sit in the fault-current hierarchy: upstream on a 100 kA-capable transformer secondary, or downstream on a 10 kA branch. The 20 kA at 440 V AC and 30 kA at 400–415 V AC cover standard 400 V three-phase distribution panels. The 10 kA at 250 V DC 2P matters for DC bus or battery-string protection.
Integration notes
Mounts fixed to a backplate — no DIN rail adapter. The 25 mm connection pitch and front-facing terminals (upside and downside) suit panel layouts where busbars or cable lugs land from the front. The toggle handle gives positive contact indication (open/closed visible). The IP20 finger-safe enclosure is standard for enclosed panels; the IK07 impact rating handles accidental tool drops during commissioning. The 13000-cycle mechanical durability is typical for distribution breakers — fine for infrequent switching, not for daily motor-start duty.
