The Siemens 3VA1196-5EF32-0JH0 is a 3-pole SENTRON molded case circuit breaker rated for 16 A continuous current at 40 °C ambient, with a full-load current rating that holds flat through 55 °C before derating to 15 A at 60 °C and above. The interrupting capacity is the headline number here: 187 kA at 240 V AC, stepping down to 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V. The rated insulation voltage is 800 V, which covers 480/277 V and 600 V systems with margin, and the maximum power loss at rated current is 10.6 W — a figure to note when calculating enclosure heat rise in a sealed panel.
The 3VA1196-5EF32-0JH0 measures 76.2 mm wide (3 in), 130 mm tall (5.12 in), and 70 mm deep (2.76 in). That 76.2 mm width is a standard 3-pole MCCB footprint — it occupies three 25.4 mm module positions on a DIN rail, so it drops into a panel already laid out for 3VA1-series breakers without re-drilling the gland plate or re-spacing adjacent devices.
