Siemens 5SY5216-7KK11 — SENTRON 2P C-curve MCB, 16 A, 10 kA
The Siemens 5SY5216-7KK11 is a SENTRON miniature circuit breaker (MCB) in a 2-pole, C-curve configuration rated at 16 A (at 35 °C) with a 10 kA breaking capacity per EN 60898. The 10 kA interrupting rating at 230/400 V AC covers most commercial and light-industrial fault levels; for DC circuits it also holds 10 kA per EN 60898-2.
Thermal derating and ambient limits
Rated current is 16 A at 35 °C, but drops to 15.02 A at 40 °C, 14.51 A at 45 °C, 13.98 A at 50 °C, 13.44 A at 55 °C, and 12.86 A at 60 °C. If the panel ambient runs warm — say, a crowded enclosure near a drive cabinet — size the load to the derated figure at your actual ambient, not the 35 °C headline.
Snap-on DIN rail mount (quick-assembly system), any orientation. The 2-pole body is 36 mm wide (2 MW), 90 mm tall, 76 mm deep with an installation depth of 70 mm.
It is designed for railway applications per its product designation. The manufacturer provides standard compliance documentation (RoHS, REACH, IEC/EN 60898) — available on request with the RFQ.
