The overload protection is adjustable from 35 A to 50 A; short-circuit pickup (Ii) is fixed at 5 to 10 times In, meaning you set the magnetic trip between 250 A and 500 A depending on the load's inrush profile. ## Deployment and integration This breaker mounts into a standard IEC panel on a DIN rail or direct-screw base. The ZD00 suffix flags a nut keeper kit for DC Power OEM assembly in China — a production-line detail that tells you the breaker ships with captive hardware for a specific OEM's panel build. If you are retrofitting into an existing 3VA1 switchboard, verify the accessory slot configuration; the TM240 trip unit is line-side lugged and accepts standard internal accessories (shunt trip, auxiliary contacts, alarm switch).","metaTitle":"Siemens 3VA1150-4EF32-0AA0-ZD00 3VA1 IEC Frame 160, 50A, 36k","metaDescription":"Siemens 3VA1150-4EF32-0AA0-ZD00 circuit breaker, 3-pole, 50A, 36kA breaking capacity at 415V.
