Siemens 3VA1196-4ED22-0AA0 — 2-Pole 16 A MCCB with 121 kA Breaking Capacity
The Siemens 3VA1196-4ED22-0AA0 is a 2-pole SENTRON molded case circuit breaker (MCCB) rated 16 A continuous at 40 °C, with a TM210 thermal-magnetic overcurrent release. Its interrupting capacity is 121 kA at 240 V AC and 75.6 kA at 415 V AC — enough for high-fault utility feeds or transformer secondaries where a standard MCB would weld. Rated insulation voltage is 500 V, operating voltage 415 V AC / 250 V DC. The front face carries IP40 protection — fine for a dry indoor panel; no washdown rating, so keep it behind a sealed enclosure door in wet environments.
Breaking Capacity and Coordination
At 121 kA (240 V AC) this MCCB sits in the high-interrupting tier of the 3VA family. That number matters for selectivity studies: if your upstream transformer can deliver 100 kA fault current, this breaker clears it without needing a current-limiting fuse ahead. The 75.6 kA at 415 V covers most European 400 V industrial panels. The TM210 release is a fixed thermal-magnetic type — no interchangeable trip units, no electronic adjustments. Thermal pickup at 1.05× In, magnetic instantaneous at 10× In typical for this design. Power loss at rated load is 7.06 W, which matters for thermal budgeting in a crowded enclosure.
Dimensions and Panel Fit
The 3VA1196-4ED22-0AA0 measures 130 mm high × 50.8 mm wide × 70 mm deep. The 50.8 mm width is two standard 25.4 mm module spaces on a DIN rail — same footprint as a 2-pole MCB, so it drops into existing panel layouts without re-drilling. Depth of 70 mm leaves room for rear-access wiring in a 200 mm deep enclosure. No undervoltage release, no shunt trip, no auxiliary contacts factory-fitted. If you need those, the 3VA platform accepts clip-on accessories, but verify compatibility with this specific variant — the TM210 base unit ships bare.
