The Siemens 3VA1196-5EF32-0AG0 is a 3-pole IEC frame 160 molded-case circuit breaker with a 55 kA interrupting capacity at 415 V (class M). The TM240 thermal-magnetic trip unit gives you adjustable overload protection (Ir = 11 A to 16 A) and fixed short-circuit protection (Ii = 10 to 20 × In, so 160 A to 320 A at the 16 A rating).
Mounts in a standard IEC frame 160 footprint — the same cut-out and bus-bar spacing as other 3VA1 breakers. The nut keeper kit retains the terminal screws during wiring, a small time-saver on a multi-breaker panel. The auxiliary and alarm switches are pre-installed and wired to the breaker's internal contacts; verify the wiring diagram for your PLC input voltage before energizing.
