The 3VA1216-6EF32-0AA0-ZD00 is a Siemens 3VA1 IEC frame 250 molded-case circuit breaker, 3-pole, with a class H interrupting rating of 70 kA at 415 V. The TM240 thermal-magnetic trip unit gives you an adjustable overload pickup (Ir) from 112 A to 160 A via a rotary dial, and a fixed magnetic short-circuit pickup (Ii) at 5 to 10 times In — so at the 160 A In setting, Ii lands between 800 A and 1600 A. That range suits motor feeders or mixed loads where you need to ride through inrush without nuisance tripping, but still clear bolted faults fast. The suffix ZD00 adds a nut keeper kit for a DC Power OEM in China — essentially a captive hardware feature for panel builders assembling DC power distribution sections. It does not change the electrical ratings; it's a mechanical packaging detail for a specific production line.
Deployment context
The nut keeper kit simplifies panel assembly for the specific OEM it was built for, but the breaker itself is a general-purpose IEC MCCB suitable for distribution, motor feeder, or backup protection in commercial and industrial switchboards.
