The Siemens 3VA1196-5EE32-0AB0 is a SENTRON 3-pole molded case circuit breaker rated for 16 A continuous at 40 °C, with a TM220 thermal-magnetic trip unit. The interrupting ratings are the headline: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V.
At 60 °C it drops to 15 A, and it holds there through 70 °C. That's a clean derating curve: you lose 1 A across a 30 °C rise above 55 °C. The maximum power loss is 10.6 W, which is modest for a 3-pole MCCB at this rating — helps keep internal panel temperature in check.
Physical fit and integration
That 76.2 mm width (3 inches) is the standard 3-pole MCCB footprint for this frame size — it occupies three 25 mm DIN positions or a bolt-on panel mount.
