Siemens 3VA5225-5EC31-0AA0 U 250A 600V 3P Circuit Breaker

Siemens 3VA5225-5EC31-0AA0 is a three-pole molded‑case circuit breaker rated for 250 A, designed for up to 600 V AC supply. It belongs to the Siemens SENTRON 3VA5 UL frame family and supports panel mounting or DIN‑rail installation with FTAM (feed‑through attachment) options, arriving complete with the TM230 trip unit. The unit provides thermal‑magnetic protection with distinct long‑time and instantaneous trip functions and is UL 489 listed. Its interrupting capacity is 18 kAic at 600 V (and 35 kAic at 480 V), enabling safe interruption of high fault currents in three‑phase systems. Configured as a 3P device, it protects distribution circuits and motor feeders up to 250 A, making it suitable for switchboards, motor control centers, and protection assemblies in industrial and commercial environments that operate at up to 600 V AC.
