The Siemens 3VA1180-6EF32-0AA0-ZD00 is a 3-pole IEC frame 160 molded-case circuit breaker rated 80 A continuous, with a 70 kA interrupting capacity at 415 V (breaking capacity class H). Overload protection is adjustable via the TM240 thermal-magnetic trip unit from 56 A to 80 A; short-circuit pickup is fixed at 5 to 10 times In. The suffix ZD00 adds a nut keeper kit for DC Power OEM assembly in China — a line-item detail that matters if your panel build expects that hardware pre-fitted. This is a current-production part (lifecycle stage: current).
Sourcing and fit for the BOM line
The 70 kA @ 415 V rating handles high-fault installations.
The nut keeper kit (ZD00 option) is a small but time-saving detail on a DC Power OEM line: it keeps the terminal nuts captive during wiring, so an assembler doesn't drop a nut into a live panel.
