This is the current-production variant, actively manufactured.
The 36 kA Icu at 380/415 V AC is the key rating for European 400 V distribution — it tells you this breaker can safely interrupt a fault current up to 36 kA without welding contacts or rupturing the case. At 240 V AC that figure climbs to 85 kA Icu, and at 480 V AC (UL 60947-4-1) it holds 35 kA.
Electrical endurance is 20,000 cycles at 440 V at half rated current, 10,000 at full rated current — expect to outlast the panel's service life in normal distribution duty.
