The SENTRON 5SY3010-6KV is a miniature circuit breaker with a B tripping characteristic, rated 10 A and a breaking capacity of 4.5 kA at 230 V AC.
The 10 A B-curve rating means this MCB trips between 3 and 5 times rated current (30–50 A) on short-circuit — standard for protecting general-purpose final circuits like lighting and socket outlets in residential and light commercial buildings. The 4.5 kA breaking capacity at 230 V AC is the maximum fault current it can safely interrupt; this is the entry-level rating for EN 60898 MCBs, adequate for most domestic and small commercial installations where the prospective short-circuit current (PSCC) at the point of installation is known to be under 4.5 kA. The 1+N-pole configuration switches both phase and neutral, with the neutral pole switching but not protecting — common in single-phase final circuits where disconnection of both conductors is required for safety isolation.
Deployment context
The 70 mm installation depth fits flush in most residential and commercial distribution boards without protruding beyond the enclosure door.
