The TM220 overload trip unit is adjustable from 350 A to 500 A, and the short-circuit pickup is fixed at 10 times the rated current (Ii = 10 x In). That 10x multiplier is a thermal-magnetic characteristic; it's not the electronic-adjust kind, so you set the overload band and the magnetic trip stays put. The N conductor is protected at 100%. This breaker mounts in a standard panel or enclosure — it's a molded-case unit, not a DIN-rail miniature, so plan for the frame 630 footprint and the lug or bus-bar connections that go with it. The description flags a nut keeper kit for DC Power OEM in China, which suggests the breaker may ship with hardware tailored for DC-side assembly; confirm the termination kit matches your bus work before the panel goes together.","metaTitle":"Siemens 3VA1450-4GE42-0AA0-ZD00 Circuit Breaker, 500A, 36kA","metaDescription":"Siemens 3VA1450-4GE42-0AA0-ZD00 circuit breaker, 3VA1 IEC frame 630, 500A, 36kA @ 415V, 4-pole, TM220 overload.
