The Siemens 5SL6316-7RC is a SENTRON miniature circuit breaker rated 16 A with a C tripping characteristic, 3 poles, and a 7.5 kA breaking capacity per EN 60898 at 415 V AC.
Voltage and frequency coverage
Rated supply voltage is 415 V AC, with multi-phase operation accepted up to 440 V AC maximum. Single-phase operation is rated at 250 V AC. The breaker handles 50/60 Hz line frequencies — no issue for standard mains anywhere. DC rating tops out at 72 V, so this is an AC-primary device; don't spec it for a DC subpanel unless you're below that ceiling.
Occupies 3 modular width units (each 18 mm, so 54 mm total) on a DIN rail. Sealable — you can lock the toggle position for tamper resistance in metered or common-area panels.
Environmental and compliance specs
Halogen-free and silicon-free construction, which matters for outgassing-sensitive environments like clean rooms or telecom shelters.
