The Siemens SENTRON 3VA1196-5EF32-0CA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a 16 A continuous current rating that holds flat from 40 °C through 50 °C — no derating needed in a typical warm enclosure. Above that, it steps down in 0.32 A increments per 5 °C, hitting 14.4 A at 70 °C. The interrupting capacity is the headline number here: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V.
Release, auxiliaries, and what is inside the can
An undervoltage release (UVR) is fitted as standard, wired to the control voltage so the breaker drops out on a brownout or a deliberate signal from an E-stop chain. There is no auxiliary contact block on this unit, no ground-fault monitoring, no phase-failure detection, and no communication module. If you need remote status feedback, the integrated auxiliary trip (order code 3VA9608-0BB24) is the path.
