The Siemens 3VA1196-6GD42-0AA0-ZD00 is a 4-pole IEC frame 160 molded case circuit breaker with a 70 kA interrupting capacity at 415 V (breaking capacity class H). It's configured for line protection with a TM210 thermal-magnetic trip unit — fixed overload protection at 16 A (Ir=16 A) and fixed short-circuit protection set at 20 x In (320 A).
The 4-pole form factor with N-conductor protection at 100% means it's suited for three-phase, four-wire systems where the neutral is treated as a current-carrying conductor — common in North American-derived distribution or where harmonic content is a concern. The nut keeper kit simplifies panel wiring by retaining hardware during assembly.
