The Siemens 5SN6232-7CP is a 2-pole miniature circuit breaker from the SENTRON 5SN family, rated for 400 V AC at 50 Hz. It carries a 6 kA breaking capacity per EN 60898 and a 15 kA rating per IEC 60947-2 — the higher figure applies when the breaker is installed in an industrial panel where the prospective fault current is known and the standard allows the industrial rating. That dual rating is the main thing to check against your panel's SCCR requirement. The 2-pole form factor (36 mm wide, 2 modular width units) snaps onto a standard DIN rail and occupies the same footprint as a typical residential double-pole MCB. Depth is 76 mm, installation depth 70 mm — leaves clearance behind a 100 mm deep enclosure back wall.
Rated for multi-phase and single-phase operation up to 440 V AC maximum — covers 400 V three-phase and 230/240 V single-phase circuits. DC rated maximum is 72 V, so it can switch a 48 V or 60 V DC control bus but not a 110 V DC battery bank. Power loss is 2.6 W per pole at rated current in hot operating state — two poles dissipate 5.2 W total. Not rated for frequent manual switching duty like a disconnect. Accepts solid conductors up to 35 mm² — enough for a 50 A feed on the line side.
