The Siemens 5SY4225-8CC is a 2-pole miniature circuit breaker from the SENTRON family, rated 25 A with a D tripping characteristic. The 10 kA breaking capacity per EN 60898 tells you it can safely interrupt a fault current up to that level on a 400 V AC supply, which covers most industrial panel secondary circuits.
Depth is 76 mm, installation depth 70 mm — standard for a 2-pole MCB, so it fits existing SENTRON or third-party distribution boards without reworking the gland plate.
10 kA per EN 60898 at 400 V AC, and 5 kA per UL 1077 / CSA C22.2 No.235. That covers most industrial panel secondary-fault scenarios.
It's sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
Both are 2-pole SENTRON MCBs on the same DIN-rail footprint, so the 5SY4225-8CC drops in without rewiring. The difference is the rating: the 5SY7206-7CC is a different current/curve variant, so verify your load before swapping.
