The Siemens 3VA1196-3EF42-0AA0-ZD00 is a 4-pole IEC frame 160 circuit breaker with a 25 kA breaking capacity at 415 V, rated for line protection in the 3VA1 series. Its thermal-magnetic trip unit (TM240, ATAM) offers adjustable overload protection from 11 A to 16 A and short-circuit protection set at 10 to 20 times the rated current In=16 A.
The adjustable Ir (11–16 A) lets you fine-tune overload protection to the connected load without swapping trip units, and the Ii range of 10–20 x In gives flexibility for motor-starting inrush or transformer magnetizing currents.
The nut keeper kit is factory-fitted to the load-side terminals, saving a step during busbar assembly. The 4-pole footprint occupies the same width as four single-pole breakers in the 3VA1 frame, so plan your DIN-rail fill factor accordingly. Derate per IEC 60947-2 when grouping multiple breakers without spacing.
