3VA5150-6ED31-0AA0 SIEMENS

The 3VA5150-6ED31-0AA0 is a 3VA5 series molded case circuit breaker (MCCB) from Siemens, designed for UL/CSA markets. It features a frame size of 125A and a high breaking capacity class H, capable of interrupting fault currents up to 65kA at 480V AC. This particular model is a 3-pole circuit breaker, suitable for protecting three-phase circuits. It is equipped with a TM210 trip unit, specifically configured for line protection applications. The TM210 trip unit offers a fixed thermal overload protection (Ir) set at 50A, safeguarding conductors from sustained overcurrents. Additionally, it incorporates a fixed magnetic short-circuit protection (Ii) set at 10 times the rated current (In), providing rapid response to high-level fault currents. The breaker is designed without connection terminals, allowing for flexible connection options based on the specific application requirements. This MCCB is ideal for use in various industrial and commercial applications where reliable and robust circuit protection is essential. Its high breaking capacity and adjustable trip settings make it suitable for a wide range of load types and fault conditions.
