At 400 V AC, the 10 kA breaking capacity per EN 60898 covers standard residential and commercial panel fault levels; the 20 kA rating per IEC 60947-2 gives headroom for industrial distribution where higher prospective fault current is expected. The 3-pole configuration switches all three phases simultaneously, which is the expected arrangement for three-phase sub-distribution boards and motor feeder protection where single-phasing must be avoided.
Because this is an active, standard-catalog SENTRON MCB, lead times typically track the manufacturer's production cycle — no unusual sourcing constraints apply.
The tunnel terminals simplify wiring: strip, insert, tighten. No special tools beyond a screwdriver. If the panel requires signaling or remote tripping, the accessory slot is available.
