The Siemens 3VA1196-5EE32-0AA0-ZD00 is a 3-pole IEC frame 160 molded-case circuit breaker with a breaking capacity class M rating of Icu=55kA at 415V. Overload protection (Ir) is adjustable from 11A to 16A; short-circuit protection (Ii) is fixed at 20 x In. The suffix ZD00 indicates a nut keeper kit included for DC Power OEM applications in China.
The 55kA Icu at 415V places this breaker in breaking capacity class M, suitable for high-fault industrial distribution panels where upstream fault current can reach that level. The TM220 trip unit provides thermal-magnetic protection: the thermal element handles overloads (Ir adjustable 11-16A), while the fixed magnetic element (Ii=20 x In) clears short-circuits. The 3-pole configuration fits three-phase line protection. The nut keeper kit (ZD00 suffix) is a mechanical accessory for secure mounting in DC Power OEM builds — not a functional electrical difference.
