The Siemens SENTRON 3VA1196-4EF32-0DC0 is a 3-pole molded case circuit breaker (MCCB) rated for 16 A continuous current at 40 °C ambient, with a breaking capacity of 121 kA at 240 V AC. At 415 V the interrupting rating drops to 75.6 kA, and at 690 V it's still 11.9 kA, so it covers both 400 V and 690 V industrial distribution without needing an upstream current-limiting fuse.
The 16 A rating holds steady from 40 °C up to 55 °C — no derating needed in a warm enclosure — then drops to 15 A at 60 °C and above. Maximum power loss is 13.1 W, which matters for thermal management in a sealed panel with multiple breakers ganged together. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard SENTRON 3VA frame size that fits the same DIN-rail or screw-mount footprint as other 3VA1 breakers. The 70 mm depth means it clears most shallow gland-plate enclosures, but always check the door-swing clearance if you're mounting it on a swing-panel.
The two auxiliary switches provide independent NO/NC contacts for status feedback; no need to order separate accessory packs for basic signaling. If you need remote trip indication or ground-fault protection, you'd step up to a different 3VA variant with those options.
