Siemens 3VA5210-6ED31-0AA0 Industrial Circuit Breaker

The Siemens 3VA5210-6ED31-0AA0 is a 3‑pole SENTRON molded‑case circuit breaker from the 3VA5 UL frame family, rated for In 100 A with a 65 kA breaking capacity at 480 V, making it suitable for protecting three‑phase feeders in industrial panels. It supports AC operation up to 690 V and DC operation up to 750 V, and uses a TM210 thermal‑magnetic release to provide overload protection with a fixed short‑circuit setting Ii = 10 × In (about 1,000 A) and Ir = 100 A; the unit weighs around 2 kg and is HACR‑type, designed for installation in control panels, machine protection, and distribution enclosures. As part of Siemens SENTRON, this MCCB combines robust protection with a compact UL frame footprint, and is identified by the model 3VA5210‑6ED31‑0AA0 (commonly cataloged with the 334493 designation).
