The Siemens 5SL6225-6MB is a 2-pole miniature circuit breaker rated 400V with a 6kA breaking capacity, B-curve trip characteristic, and 25A rated current. This is a current-production part from the Basic Devices family, confirmed active per the manufacturer's lifecycle status.
The 25A rating per pole matches a 25A busbar or feeder tap. As a 2-pole device, it switches both phase conductors simultaneously, which is standard for single-phase 230V line-to-neutral circuits in IEC panels or for two legs of a three-phase system where neutral protection is handled separately.
RoHS compliant since 13-10-73 (date code format). Export control: AL N / ECCN N — no license required for most destinations. Product class B: return restricted — contact your Siemens partner for RMA or warranty handling. This is a standard commercial restriction, not a technical limitation.
