The 3VA1196-5EF42-0AA0-ZD00 is a 4-pole IEC frame 160 molded-case circuit breaker with a breaking capacity class M rating of Icu=55kA at 415V. The TM240 trip unit gives thermal-magnetic overload protection with an adjustable Ir from 11A to 16A (set via the ATAM dial) and a fixed short-circuit pickup Ii of 10 to 20 times In, so it's sized for a 16A line feeding a motor or distribution subfeed where you need to coordinate with downstream breakers.
Deployment context
The nut keeper kit indicates use in a DC power distribution assembly for an OEM in China.
