What this MCCB delivers — and where the rating matters
The Siemens SENTRON 3VA1196-4EF36-0AD0 is a 3-pole molded case circuit breaker (MCCB) rated for 16 A continuous current with a TM240 thermal-magnetic release. Its interrupting capacity hits 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V — numbers that tell you it's built for high-fault locations like transformer secondaries or large motor control centers where available fault current is stiff. The 16 A rating holds flat from 40 °C to 50 °C; above that it starts a gentle derate — 15.36 A at 55 °C, down to 14.4 A at 70 °C. If your panel ambient runs hot, the continuous current you can actually carry is the derated value, not the nameplate 16 A. Rated insulation voltage Ui is 800 V. The front face carries IP40 protection.
Panel fit and integration notes
Footprint is 76.2 mm wide, 130 mm tall, 70 mm deep — standard 3-pole MCCB spacing. Mounts on a DIN rail or direct panel; the 70 mm depth means it clears most shallow enclosures without a sub-panel offset. Comes with 3 auxiliary switches (HQ type) built in — no separate add-on block needed for status feedback to a PLC or indication lamp. No undervoltage release, no shunt trip, no communication module on this variant; if you need those, you're looking at a different suffix in the 3VA family.
