The SENTRON 5SP4250-8 is a 2-pole miniature circuit breaker from the 5SP4 design family, rated 50 A at 400 V AC with a D tripping characteristic.
Installation depth is 70 mm — fits standard DIN-rail enclosures without bottoming out against the gland plate. Two-pole format (2P) switches both phase conductors, so it suits single-phase or split-phase subfeeds where you need full isolation.
The part is sourced to order against an RFQ through independent distribution channels. Submit an RFQ for current availability and pricing — confirmed at quote time, not from a static listing.
The 5SP4292-7 is the same 2-pole 5SP4 family and same 70 mm depth, but it carries a C-curve instead of D-curve and is rated 440 V instead of 400 V. The D-curve on the 5SP4250-8 is the deciding factor for motor/transformer loads — a C-curve swap may nuisance-trip on high inrush. Footprint and tunnel terminals are identical, so a panel wired for the 5SP4292-7 accepts the 5SP4250-8 without rewiring, but the trip curve mismatch matters for the load type.
The part carries EN 60898 and IEC 60947-2 ratings, which implies CE marking for the European market. RoHS and REACH compliance is standard for current SENTRON production. For specific declarations or UL listing, verify against the nameplate or request the manufacturer's declaration with your RFQ.
