The Siemens 3VA1196-5EF32-0DC0 is a SENTRON molded case circuit breaker (MCCB) rated for 16 A continuous current across the 40 °C to 55 °C ambient range, derating to 15 A at 60 °C through 70 °C. Its headline breaking capacity hits 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V — figures that handle high-fault industrial feeds without cascading upstream.
The 121 kA at 415 V and 75.6 kA at 440 V cover common three-phase distribution voltages in industrial plants. At 500 V and 690 V the rating drops to 17 kA, still adequate for most 480/600 V motor control centers but not for ultra-high-fault petrochemical switchgear. Above that, it steps to 15 A at 60 °C through 70 °C. The 13.1 W maximum power loss means the breaker dissipates that heat into the enclosure; factor it into your panel thermal budget if you're packing multiple units side by side.
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without re-drilling.
