What this MCCB carries and where it fits
The Siemens 3VA1196-5EF36-0KA0 is a SENTRON 3VA molded case circuit breaker — 3-pole, 16 A continuous rating, with a TM240 thermal-magnetic release. The interrupting ratings climb to 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. That's a lot of fault-current headroom for a 16 A frame; it means this breaker can sit upstream of a high-available-fault panel without needing a current-limiting fuse ahead of it. The shunt trip (STL) release lets you drop the breaker remotely from an E-stop or PLC output, which is handy for a machine disconnect or a safety circuit that needs to kill power without pulling a handle.
Thermal derating and panel integration
Rated 16 A up to 50 °C ambient (–); above that it derates linearly to 14.4 A at 70 °C. If this breaker lands in a crowded enclosure near drives or transformers, expect to knock the load down by about 10% at 65 °C. Dimensions are 76.2 mm wide, 130 mm tall, 70 mm deep — standard 3VA frame footprint, so it drops into a panel cutout or DIN-rail adapter without surprises. IP40 on the front means it's fine inside a closed cabinet; keep it out of washdown zones.
