The Siemens 3VA1196-4ED12-0AA0 is a SENTRON 3VA1 molded case circuit breaker (MCCB) designed for line protection in a 1-pole configuration. It carries a continuous current rating of 16 A at 40 °C (derating to 15 A at 60 °C and above), with a TM210 thermal-magnetic release that provides fixed overload and short-circuit protection curves suited for feeder and branch circuits in industrial panels.
Breaking capacity and selectivity
The interrupting rating is 75.6 kA at 240 V AC and 9 kA at 415 V AC — a wide gap that tells you this breaker is optimized for 240 V line-to-neutral or line-to-ground fault duty typical in North American split-phase panels, not for 400 V three-phase feeders where the 9 kA figure governs. At 415 V the 9 kA SCCR is modest; coordinate downstream to avoid cascading trip if fault current exceeds that level. Rated insulation voltage is 500 V, and the operating voltage at AC is 415 V, so the breaker is electrically rated for 400 V-class systems but the interrupting capacity at that voltage is the limiting factor for fault handling.
Physical fit and panel integration
Width is 25.4 mm (1 inch) — a single pole module that snaps onto standard DIN rail. Depth is 70 mm, height 130 mm. The front face carries IP40 protection, meaning tools and fingers are kept out but the enclosure is not sealed against moisture; mount inside a rated panel for washdown or outdoor environments.
