The thermal-magnetic release is a TM210, set fixed at 20 A (Ir = In) with a short-circuit pickup of 16× In, so it protects a 20 A feeder or load circuit against sustained overloads and instantaneous faults. The nut keeper kit variant (ZD00 suffix) is configured for DC Power OEM applications in China, with box terminals on both sides and front connection. The TM210 release with Ii = 16 × In (320 A instantaneous pickup) is a line-protection curve — it is not a motor-protection or generator curve, so it is sized for cable and busbar protection, not for starting inrush. The 20 A fixed rating means no adjustment band; you order the exact amp rating the branch circuit needs. The 3VA1 frame is a standard panel-mount MCCB — 76.2 mm wide, 130 mm tall, 70 mm deep — with front terminals and box lugs on both sides. It accepts stranded conductors up to 70 mm² per pole. The IP40 front protection is typical for enclosed distribution boards; no additional sealing is needed inside a rated panel. The nut keeper kit (ZD00) is a mechanical detail for the DC Power OEM variant — it retains the terminal nuts during assembly in high-vibration or high-throughput production.","metaTitle":"Siemens SENTRON 3VA1120-5ED32-0AA0-ZD00 MCCB, 55kA @ 415V, 2","metaDescription":"Siemens SENTRON 3VA1120-5ED32-0AA0-ZD00 molded case circuit breaker, IEC frame 160, 55kA @ 415V, 3-pole, TM210 release, 20A fixed.

The difference is the release: this one is a TM210 line-protection breaker at 20 A fixed, while the 3VA1110-5MH36-0AA0 is a starter-protection version with a TM120M release. They are not electrically interchangeable for the same protection function — verify the trip curve and amp rating against your load before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1120-5ED32-0AA0-ZD00","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3VA1120-5ED32-0AA0-ZD00 when reusing this data.
