Siemens 3VA4150-4ED34-0AA0 NN 50A 600V 3P Molded Case Circuit Breaker

Siemens 3VA4150-4ED34-0AA0 is a three‑pole, 50 A molded‑case circuit breaker from the Sentron 3VA41 family, designed for protection and isolation of 600 V class feeders in industrial and commercial panels. Housed in a 125 A UL frame, it uses a thermal‑magnetic TM210 trip unit to provide overload protection with fixed short‑circuit settings (Ir = 50 A) and a short‑circuit pickup (Ii = 10 × In). The device is rated for 600 V AC (line‑to‑line) and offers a breaking capacity of 25 kA at 480 V and 14 kA at 600 V, making it suitable for a range of feeder and motor applications. It is configured for 3P operation with load‑lug connections and accepts aluminum conductors from 8 AWG to 3/0 AWG. The unit is specified for indoor panel installations with an enclosure rated around IP40 and operating temperatures from −25 °C to 70 °C. Dimensions approximate 5.5 inches high, 3 inches wide, and 3.7 inches deep, enabling compact integration in standard enclosures. Typical use cases include protecting motors, conveyors, and other 3‑phase loads in industrial power distribution, where reliable TM210 protection and coordinated short‑circuit isolation are required. This MCCB is part of Siemens’ 3VA41 series, commonly equipped with load‑side lug options and (where specified) FTFM features for enhanced fault‑to‑fault coordination.
