The Siemens Betagard 5SL7432-8RC is a 4-pole miniature circuit breaker (MCB) with a D tripping characteristic, rated 32 A at 415 V AC. It breaks fault currents up to 15 kA per both EN 60898 and IEC 60947-2 — that's the same rating under either standard, so you don't need to derate when switching between residential and industrial specs.
Where it goes and how it fits
Snaps onto a DIN rail — any mounting position works, which saves head-scratching in a tight enclosure. At 18 mm wide (4 modular width units) and 76 mm deep, it leaves room for adjacent devices. The 70 mm installation depth means it clears most standard distribution board covers.
The 15 kA breaking capacity at 415 V AC is the same under EN 60898 (household / commercial) and IEC 60947-2 (industrial) — that's unusual and simplifies spec'ing across mixed environments. Each pole dissipates 2.6 W at rated current in hot state; four poles add about 10.4 W total heat to the enclosure, so factor that into your thermal budget if the panel is densely packed. Vibration-resistant per IEC 60068-2-6, and rated for 10,000 mechanical operating cycles — typical for an MCB in a distribution board that sees occasional switching, not daily load-break duty.
