The 3 kA SCCR is the key fit constraint: this breaker interrupts faults up to that level safely. If your panel's prospective short-circuit current exceeds 3 kA at the point of installation, this unit won't hold — you need the 10 kA variant (like the 5SL4363-7) for higher-fault locations. Snaps onto a standard 35 mm DIN rail — 3 modular width units (54 mm wide), 76 mm deep, 90 mm tall. IP20 with connected conductors, meaning it's protected against finger contact inside an enclosed panel but not against washdown or dust ingress. ## What it's not — and when you need the bigger sibling The closest functional peer is the 5SL4363-7 — same 3-pole C-curve footprint, but rated 63 A with a 10 kA breaking capacity per IEC 60947-2. The 5SL1316-7MB is the 16 A, 3 kA entry. Otherwise, the 5SL1316-7MB drops into the same DIN-rail slot with the same wiring pattern — no rewiring needed for a like-for-like swap at the same rating. ## Thermal and endurance notes Dissipates 1.9 W per pole in hot operating state at rated current — 5.7 W total for the 3-pole assembly. Mechanical service life is 4,000 operating cycles typical; not a high-cycle switching device, but fine for overcurrent protection duty where it trips rarely.","metaTitle":"Siemens 5SL1316-7MB SENTRON MCB, 3P C 16A, 3kA IEC 60947-2","metaDescription":"Siemens 5SL1316-7MB SENTRON miniature circuit breaker, 3-pole, C-curve, 16A, 3kA breaking capacity per IEC 60947-2.
