The Siemens SENTRON 3VA1196-4EF36-0DA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, with a continuous current Iu of 16 A and an interrupting capacity of 75.6 kA at 415 V. The TM240 release provides a fixed thermal curve for overloads and a magnetic trip for short-circuits, so it's a straightforward drop-in for standard feeder or branch protection.
The breaker is rated 16 A continuously from 40 °C through 50 °C, then derates linearly to 14.4 A at 70 °C. Dimensions are 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that fits most Siemens SENTRON distribution boards and third-party enclosures with DIN-rail or screw-mount adapters. Front protection is IP40, so it's fine for indoor panel use but needs a cover or higher-rated enclosure if washdown or dust is present.
