Integrator's terse spec recap
The Siemens SENTRON 3VM1196-3ED16-0AA2 is a 1-pole molded case circuit breaker (MCCB) in the 3VM line, carrying a TM210 thermal-magnetic overcurrent release with LI protection (long-time and instantaneous). Rated 16 A continuously from 40 °C through 55 °C, it derates to 15 A at 60 °C and holds that to 70 °C — no further drop above 55 °C until the upper ambient limit. The switching capacity class is N (normal), delivering 53 kA at 240 V AC and 8 kA at 415 V AC. Max rated operational voltage is 500 V AC 50/60 Hz; DC rating is 125 V. The front face carries IP40 protection, suitable for enclosed panel mounting.
DIN-rail panel fit
The breaker occupies a single 25.4 mm (1 in) width slot on the DIN rail, with a depth of 70 mm (2.8 in) and height of 130 mm (5.1 in). The 1-pole form factor leaves adjacent slots free for additional poles or auxiliary devices. Power loss is rated at 4 W maximum — negligible for thermal budgeting in a crowded enclosure.
