The Siemens 3VA1196-6EF32-0AG0 is a SENTRON molded case circuit breaker (MCCB) designed for line protection, carrying a continuous current rating of 16 A at 40 °C and derating to 15 A at 70 °C. Its interrupting capacity hits 220 kA at 240 V, 154 kA at 415 V, and still holds 17 kA at 690 V — meaning it can clear a bolted fault on a 480 V distribution bus without upstream coordination headaches.
Interrupting & continuous ratings
Three-pole construction with a TM240 thermal-magnetic release. The 16 A frame holds steady across 40–55 °C ambient, then drops to 15 A at 60–70 °C — that derating curve matters if this breaker sits in a crowded, hot panel. Rated insulation voltage is 800 V, so it's comfortable on 480/277 V or 600 V systems with headroom. Interrupting capacity falls off as voltage climbs: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, then a sharp drop to 17 kA at 500 V and 690 V. On a 480 V corner-grounded delta or 400 V wye, you've got serious fault-clearing muscle; above 500 V, the 17 kA limit means you need to verify the available fault current at the panel.
Physical fit & auxiliary switch
Dimensions: 130 mm high, 76.2 mm wide, 70 mm deep. That 70 mm depth is shallow enough for most 200 mm deep enclosures without door interference. The breaker ships with one auxiliary switch and one trip alarm switch (HP type) — enough for a remote open/closed and trip indication back to a PLC input.
