At 30 °C ambient it carries the full 16 A; at 40 °C it derates to 15.2 A, and at 45 °C to 14.88 A. That derating matters if the breaker sits in a warm enclosure — plan the load accordingly. The 1.6 W power loss per pole at rated current in hot operating state adds up to 6.4 W total for the 4-pole unit, which should be factored into enclosure thermal calculations. ## Mounting and integration Snaps onto DIN rail in any mounting position. Occupies 4 modular width units (each 18 mm, so 72 mm total width). Installation depth is 70 mm; overall depth is 76 mm. The IP20 rating with connected conductors means it's protected against finger contact but not water ingress — standard for enclosed distribution boards. Sealable design allows locking the toggle position for anti-tamper requirements. Supplementary devices (auxiliary switches, shunt trips, under-voltage releases) can be installed on the side. ## Environmental and compliance Halogen-free and silicon-free construction — relevant for environments sensitive to corrosive off-gassing (data centers, clean rooms, marine). Operating temperature range from -40 °C to 75 °C covers extreme cold storage and hot panel conditions. Pollution degree 2 and overvoltage category III suit fixed installations in building distribution. The energy limitation class 3 means it limits let-through energy effectively for downstream equipment protection. ## Sourcing and lifecycle The lifecycle stage is current — no end-of-life notice, no last-time-buy window. This is a standard catalog item from the SENTRON family, so it's straightforward to specify into a BOM. Quoted to order against an RFQ; availability and current pricing confirmed at quote time.","metaTitle":"Siemens 5SL6616-7MB SENTRON MCB, 3P+N, C-16A, 6kA","metaDescription":"Siemens 5SL6616-7MB SENTRON miniature circuit breaker, 3P+N, C characteristic, 16 A, 6 kA breaking capacity per EN 60898 / IEC 60947-2.
